Function with arguments and return value in C

Function with arguments and return value

     In this section  function takes arguments  and returns some value.
Syntax :

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

// C code for function with arguments  // and with return value    #include <stdio.h> #include <string.h> int function(int, int[]);    int main() {     int i, a = 20;     int arr[5] = { 10, 20, 30, 40, 50 };     a = function(a, &arr[0]);     printf("value of a is %d\n", a);     for (i = 0; i < 5; i++) {         printf("value of arr[%d] is %d\n", i, arr[i]);     }     return 0; }    int function(int a, int* arr) {     int i;     a = a + 20;     arr[0] = arr[0] + 50;     arr[1] = arr[1] + 50;     arr[2] = arr[2] + 50;     arr[3] = arr[3] + 50;     arr[4] = arr[4] + 50;     return a; }

Output:

value of a is 40
value of arr[0] is 60
value of arr[1] is 70
value of arr[2] is 80
value of arr[3] is 90
value of arr[4] is 100
