Function Syntax In C

Function Syntax In C

In this article we will show you the solution of function syntax in C, firstly we understand the what is syntax. In simple language we can say that syntax is the structure of statements in a computer language.

Now, let us understand the concept of function syntax in C Language.

Step By Step Guide On Function Syntax In C :-

The syntax of a computer language is the rules that defines the combinations of symbols that are considered to be rightly structured statements or expressions in that language.

A function is a set of statements that simultaneously execute a assignment.

The C standard library provides many made up- in functions that your program can call.

A function can also be appertained as a system or a sub-routine or a procedure, etc.

Now we can say that the function syntax is nothing but it is the syntax of functions which we used in the C language Program.

Following is the syntax function :-

return_type function_name(data_type parameter...)
 body of function //code to be executed

Let us understand the above syntax :-

Return Type: A function may restore a value. The return_type is the data type of the value the function comebacks.

Some functions execute the asked details without restoring a value. For that, the return_type is the keyword void.

Function Name - This is the genuine name of the function. The function name and the parameter list simultaneously form the function hand.

Parameters - A parameter is nothing but it is a placeholder. When a function is invoked, you transfer a value to the parameter. This value is applied to as genuine parameter or argument. The parameter list refers to the type, arrangement, and number of the parameters of a function. Parameters are elective; that is, a function may hold no parameters.

Function Body - The function body contains a library of statements that outline what the function does.

#include <stdio.h>
void myFunction() {
  printf("Welcome to Talkerscode!\n");
int main() {
  return 0;
  1. In first line of the code we use pre-processor directory and header file for standard library.
  2. Then we use return_type as a void and after that we create a function named as void myFunction.
  3. myFunction is nothing but it is the name of function which we created.
  4. After that you can see that there is nothing between parentheses. It means we are not providing any type of parameters. We create the simple program.
  5. Then you can see that our function body in which we write the statement which we have to print in our output by using printf.
  6. After creating function we have to call the function for running our C program.
  7. Then our main function starts where we call our function. We call our function multiple times.
  8. At the end of code we write return 0 it means or program executed successfully.

Conclusion :-

Hence, we have successfully learnt about the syntax of function in C language.

We learnt that it is nothing but the structure of creating function in C Language.

I hope this article on function syntax in C helps you and the steps and method mentioned above are easy to follow and implement.
