No Return With Argument Function in C

In C programming, a function that takes one or more arguments but does not return a value is called a void function. The syntax for defining a void function with arguments is as follows:

        Syntax :
           return_type function_name ( data_type argument1, data_type argument2, ... ) // Function Definition
           {
                 // body of Statement ;
           }

Here, the 'void' keyword is used as the return type to indicate that the function does not return any value. The function_name is the name of the function, and the argument1, argument2, ... are the input parameters that the function takes.
A void function with arguments can be called by providing the values for the arguments in the function call:

function_name(value1, value2, ...);

This program is a simple C program that demonstrates how to define and call a void function in C. The program defines a void function called add that takes two integer parameters, x and y, and adds them together. The function then prints the result of the addition.
The main function first prompts the user to enter two integers, a and b, which are then passed as arguments to the add function when it is called. The add function uses these arguments as its x and y parameters and performs the addition. The result of the addition is then printed to the console.
