What are the benefits of using functions?

Answer 1

A static function in class scope (within a class) can access only static class members (for all instances of the class).  A static function in file scope (not within a class) is visible only to code within that compilation unit, i.e. it cannot be linked from file to file.

Answer 2

Functions are used for a few main reasons.

First, if you made a mistake you only need to fix it in one part of your code. If you had copied and pasted your function into dozens of parts of your project, there's a good chance you'll forget about some of them while trying to fix your bug.

Second, it will (or should) make your code easier to read. Functions with descriptive names are far more useful for describing what code does than comments.

Third, if you have a particularly large function which is called often, you will have much more concise code than if that code was not in a function. This helps with both readability and memory footprint.

Answer 3

Functions are key features of any programming language. This is because they allow programmers to break a problem into smaller chunks that solve the big problem. Apart from this they allow parts of the programming code to be reusable.

Answer 4

It increases readability and functionality of a program.

As an afterthought. The main advantages of using functions in C programming is that you have to have at least 1 function if you want to write a program.

int main(int a, char **c)

Answer 5

Benefits of using functions are:

1. Modularity

2. Reusability

3. Reduces program memory requirement

4. Same function can be accessed by multiple tasks (in a memory mapped environment)

Answer 6

You cannot write a C program without functions.

Function increase the understanding of program.

Function is reusable code ,if you want to call the function by single definition.

Answer 7

function is a self contained sub-block statement.it is used to save the memory space.

Answer 8

The 3 main advantages of functions are:

1.Re-usability.

2.We can call it from anywhere of the program.

3.User-defined functions can also created.

Answer 9

to make the program easy to understand ..also there can be many blocks in the function.so it becomes more easy to read and understand it.
