Which of the following statement(s) about global variables is(are) true?
A) If a function contains a local variable with the same name as a global variable, the global variable's name takes precedence within the function. B) A global variable can have the same name as a variable that is declared locally within a function C) A global variable is the same as a named constant. D) A global variable is declared in the highest level block in which it is used. E) A global variable is accessible only to the main function.

Answers

Answer 1

The statement about global variable true is :

A local variable declared inside of a function can have the same name as a global variable.

What is meant by Global variable ?

As the name suggests, global variables are variables that are available everywhere in the application. They are stored in memory for the duration of the programme after being declared. This implies that they are changeable at any time by any function and may have an impact on the entire programme.

Global variables are those that have been declared outside of the specified function. These are not restricted to a particular function, therefore any available function can be used to access and alter global variables.

Global variables are those that are produced outside of a function, like in all of the aforementioned cases. Everyone can use global variables, both inside and outside of functions.

What is a memory module?
Memory-integrated circuits are installed on a printed circuit board known as a memory module or RAM stick in computing. In electronic systems, particularly PCs like personal computers, workstations, and servers, memory modules allow for simple installation and replacement. They are always found within the computer case because memory modules plug directly into the motherboard. The computer must be turned off and the casing opened in order to access the modules before you may reinstall RAM.

a(n) _____ scans the entire source code, looking for errors in the form of the code.

Answers

A compiler is one that scans the entire source code, looking for errors in the form of the code.

What is a compiler and use of it?

A compiler is a language processor that reads a whole source program written in a high-level language in one go and converts it into an equivalent program written in machine code. Example: Java, C, C++, and C#.

Uses of a compiler: Some advance compilers have multiple languages interfaces like they have python 3 and java script etc along with that the compilers actively show the errors in the program done. So online compliers are also being used without downloading the entire software.

Hence we can conclude that the compiler scans the entire source code, looking for errors in the form of the code.

Answers

It is true that the logical OR datapath component should be instantiated for the transition condition.

What's a data path?

A data path is a collection of functional units that perform data processing operations. A computer system's CPU (central processing unit) is made up of datapaths and a control unit. Multiplexers can be used to join multiple data paths together to create a larger data path.

A datapath is a collection of functional units that perform data processing operations, such as arithmetic logic units or multipliers, as well as registers and buses.

The central processing unit is made up of the control unit and the central processing unit (CPU). Multiplexers can be used to join multiple datapaths together to create a larger datapath.

Memory (which stores the current instruction), PC or program counter (which stores the address of the current instruction), and ALU are examples of simple datapath components (executes current instruction).

In this case, this is true because there is transition of both signal or condition ( whatever ) K>6 and !((K>6||!j) . Otherwise mixing them will cause an error.
