Takes something returns nothing functions in C

 When a function has arguments, it receive any data from the calling function but it returns no values.

Syntax :

Function declaration : void function ( int );
Function call : function( x );
Function definition:
             void function( int x )
             {
               statements;
             }

// C code for function  // with argument but no return value #include <stdio.h>    void function(int, int[], char[]); int main() {     int a = 20;     int ar[5] = { 10, 20, 30, 40, 50 };     char str[30] = "Study for future";     function(a, &ar[0], &str[0]);     return 0; }    void function(int a, int* ar, char* str) {     int i;     printf("value of a is %d\n\n", a);     for (i = 0; i < 5; i++) {         printf("value of ar[%d] is %d\n", i, ar[i]);     }     printf("\nvalue of str is %s\n", str); }

Output:

value of a is 20
value of ar[0] is 10
value of ar[1] is 20
value of ar[2] is 30
value of ar[3] is 40
value of ar[4] is 50
The given string is "Study for future"
