Call By Reference

 #include<stdio.h>

int swap(int *a, int *b);

int main()

{

    int x = 4, y = 8;

    printf("The value of x and y before swap is : %d and %d\n", x,y);

    swap(&x,&y);

    printf("The value of x and y before swap is : %d and %d\n", x,y);

return 0;

}

int swap(int *a, int *b){

    int temp;

    temp = *a;

    *a = *b;

    *b = temp;

}

OUT PUT--->

The value of x and y before swap is : 4 and 8 The value of x and y before swap is : 8 and 4

Call By Value

 #include<stdio.h>

int sum(int a, int b);

 

int main()

{

    int a=99,b=12;

    printf("The value of 99 + 12 is: %d", sum(a,b));

 

return 0;

}

int sum(int a, int b){

    return a+b;

}

ANS--->

The value of 99 + 12 is: 111
