Answer:
The program in Python is as follows
def Paths(row,col):
if row ==0 or col==0:
return 1
return (Paths(row-1, col) + Paths(row, col-1))
row = int(input("Row: "))
col = int(input("Column: "))
print("Paths: ", Paths(row,col))
Explanation:
This defines the function
def Paths(row,col):
If row or column is 0, the function returns 1
if row ==0 or col==0:
return 1
This calls the function recursively, as long as row and col are greater than 1
return (Paths(row-1, col) + Paths(row, col-1))
The main begins here
This prompts the user for rows
row = int(input("Row: "))
This prompts the user for columns
col = int(input("Column: "))
This calls the Paths function and prints the number of paths
print("Paths: ", Paths(row,col))
You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???
Along with the encrypted copy, some mysterious person has also given you the following documents:
helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.
hints.txt -- Seems important.
In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:
decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")
Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).

Explanation:
Write a C program that right shifts an integer variable 4 bits. The program should print the integer in bits before and after the shift operation. Does your system place 0s or 1s in the vacated bits?
Solution :
#include<[tex]$\text{stdio.h}$[/tex]>
#include<conio.h>
void dec_bin(int number) {
[tex]$\text{int x, y}$[/tex];
x = y = 0;
for(y = 15; y >= 0; y--) {
x = number / (1 << y);
number = number - x * (1 << y);
printf("%d", x);
}
printf("\n");
}
int main()
{
int k;
printf("Enter No u wanted to right shift by 4 : ");
scanf("%d",&k);
dec_bin(k);
k = k>>4; // right shift here.
dec_bin(k);

The function turn_to_letter decides on the letter grade of the student according to the table below from the visa and final grades sent into it and returns it, write it together with a main function which the turn_to_letter function is called and prints the letter equivalent on the screen. -Success score = 40% of midterm + 60% of final,
-F for the success score below 50, D for between 50 and 59, C for between 60 and 69, B for between 70 and 79, A for 80 and above.
Answer:
The program in C is as follows:
#include <stdio.h>
char turn_to_letter(double score){
char lettergrade = 'A';
if(score>=80){ lettergrade = 'A'; }
else if(score>=70){ lettergrade = 'B'; }
else if(score>=60){ lettergrade = 'C'; }
else if(score>=50){ lettergrade = 'D'; }
else{lettergrade = 'F';}
return lettergrade;
}
int main(){
int midterm, final;
double score;
printf("Midterm: "); scanf("%d", &midterm);
printf("Final: "); scanf("%d", &final);
score = 0.4 * midterm + 0.6 * final;
printf("Score: %lf\n", score);
printf("Letter Grade: %c",turn_to_letter(score));
return 0;
}
Explanation:
The function begins here
char turn_to_letter(double score){
This initializes lettergrade to A
char lettergrade = 'A';
For scores above or equal to 80, grade is A
if(score>=80){ lettergrade = 'A'; }
For scores above or equal to 70, grade is B
else if(score>=70){ lettergrade = 'B'; }
For scores above or equal to 60, grade is C
else if(score>=60){ lettergrade = 'C'; }
For scores above or equal to 50, grade is D
else if(score>=50){ lettergrade = 'D'; }
Grade is F for other scores
else{lettergrade = 'F';}
This returns the letter grade
return lettergrade;
}
The main begins here
int main(){
This declares the midterm and final scores as integer
int midterm, final;
This declares the total score as double
double score;
These get input for midterm score
printf("Midterm: "); scanf("%d", &midterm);
These get input for final score
printf("Final: "); scanf("%d", &final);
This calculates the total score
score = 0.4 * midterm + 0.6 * final;
This prints the calculated total score
printf("Score: %lf\n", score);
This calls the turn_to_letter function and prints the returned letter grade
printf("Letter Grade: %c",turn_to_letter(score));
return 0;
}

Write a MIPS assembly language program that prompts for a user to enter a series of floating point numbers and calls read_float to read in numbers and store them in an array only if the same number is not stored in the array yet. Then the program should display the array content on the console window.
Consult the green sheet and the chapter 3 for assembly instructions for floating point numbers. Here is one instruction that you might use:
c.eq.s $f2, $f4
bc1t Label1
Here if the value in the register $f2 is equals to the value in $f4, it jumps to the Label1. If it should jump when the value in the register $f2 is NOT equals to the value in $f4, then it should be:
c.eq.s $f2, $f4
bc1f Label1
To load a single precision floating point number (instead of lw for an integer), you might use:
l.s $f12, 0($t0)
To store a single precision floating point number (instead of sw for an integer), you might use:
s.s $f12, 0($t0)
To assign a constant floating point number (instead of li for an integer), you might use:
li.s $f12, 123.45
To copy a floating point number from one register to another (instead of move for an integer), you might use:
mov.s $f10, $f12
The following shows the syscall numbers needed for this assignment.
System Call System Call System Call
Number Operation Description
2 print_float $v0 = 2, $f12 = float number to be printed
4 print_string $v0 = 4, $a0 = address of beginning of ASCIIZ string
6 read_float $v0 = 6; user types a float number at keyboard; value is store in $f0
8 read_string $v0 = 8; user types string at keybd; addr of beginning of string is store in $a0; len in $a1
------------------------------------------
C program will ask a user to enter numbers and store them in an array
only if the same number is not in the array yet.
Then it prints out the result array content.
You need to write MIPS assembly code based on the following C code.
-------------------------------------------
void main( )
{
int arraysize = 10;
float array[arraysize];
int i, j, alreadyStored;
float num;
i = 0;
while (i < arraysize)
{
printf("Enter a number:\n");
//read an integer from a user input and store it in num1
scanf("%f", &num);
//check if the number is already stored in the array
alreadyStored = 0;
for (j = 0; j < i; j++)
{
if (array[j] == num)
{
alreadyStored = 1;
}
}
//Only if the same number is not in the array yet
if (alreadyStored == 0)
{
array[i] = num;
i++;
}
}
printf("The array contains the following:\n");
i = 0;
while (i < arraysize)
{
printf("%f\n", array[i]);
i++;
}
return;
}
Here are sample outputs (user input is in bold): -- note that you might get some rounding errors

17. What are the basic modes of operation of 8255?Write the features of mode 0 in 8255?
Answer:
There are two basic operational modes of 8255:
Bit Set/Reset mode (BSR mode).
Input/Output mode (I/O mode).
Features of 8255 Microprocessor:
Mode 0 : Simple Input/Output.
Mode 1 : Input/Output with handshake.
Mode 2 : Bi-directional I/O data transfer.
It has three 8-bit ports : Port A, Port B, and Port C, which are arranged in two groups of 12 pins.
The 8255 can operate in 3 I/O modes : (i) Mode 0, (ii) Mode 1, & (iii) Mode 2.
Can someone plz answer these questions
Answer:
11001100 = 204
11111111 = 255
Explanation:
For 11001100:
1*2⁷ + 1*2⁶ + 0*2⁵ + 0*2⁴ + 1*2³ + 1*2² + 0*2¹ + 0*2⁰ = 204
Just replace 1's by 0's in the following calculation to do it for every 8 bit number:
1*2⁷ + 1*2⁶ + 1*2⁵ + 1*2⁴ + 1*2³ + 1*2² + 1*2¹ + 1*2⁰ = 255
If you don't want to do the calculation yourself, you can set the windows calculator in programmer mode, then select binary and key in the number.

LAB: Contact list A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe 123-5432 Linda 983-4123 Frank 867-5309 Frank the output is: 867-5309
Answer:
The program in Python is as follows:
n = int(input(""))
numList = []
for i in range(n):
word_pair = input("")
numList.append(word_pair)
name = input("")
for i in range(n):
if name.lower() in numList[i].lower():
phone = numList[i].split(" ")
print(phone[1])
Explanation:
This gets the number of the list, n
n = int(input(""))
This initializes list
numList = []
This iterates through n
for i in range(n):
This gets each word pair
word_pair = input("")
This appends each word pair to the list
numList.append(word_pair)
This gets a name to search from the user
name = input("")
This iterates through n
for i in range(n):
If the name exists in the list
if name.lower() in numList[i].lower():
This gets the phone number associated to that name
phone = numList[i].split(" ")
This prints the phone number
print(phone[1])
