FAQs on C++ Programming Tutorials - Functions Video Lecture - Learn to Program with C++: Beginner to Expert - Back-End Programming
| 1. What is a function in C programming? |  |
Ans. A function in C programming is a block of code that performs a specific task. It is reusable and can be called multiple times within a program. Functions help in modularizing the code and improving code readability and maintainability.
| 2. How to define a function in C programming? | |
Ans. To define a function in C programming, you need to provide the function declaration followed by the function body. The function declaration includes the return type, function name, and parameters (if any). The function body contains the code that is executed when the function is called.
| 3. What is the use of return statement in a function? | |
Ans. The return statement in a function is used to exit the function and return a value to the calling code. It can be used to return a specific result or data back to the caller. If the return statement is not provided or void is used as the return type, the function will not return any value.
| 4. Can a function return multiple values in C programming? | |
Ans. No, a function cannot return multiple values in C programming. However, you can achieve this by using pointers or structures. By passing pointers as parameters to the function, you can modify the values inside the function and access them outside the function. Similarly, structures can be used to bundle multiple values and return them as a single value.
| 5. How to call a function in C programming? | |
Ans. To call a function in C programming, you need to use the function name followed by parentheses. If the function has parameters, you need to provide the values or variables corresponding to those parameters inside the parentheses. The function call statement can be placed anywhere in the program where you want the function to be executed.
