C program to pass arguments to a user-defined function by value and by reference

In this tutorial, we are going to write a C program to pass arguments to a user-defined function by value and by reference in C Programming with practical program code and step-by-step full complete explanation.

C program to pass an argument to a user-defined function by value and by reference.

 
#include<stdio.h>
#include<conio.h>

void main()
{
    
    int k,m,other(int,int*);

    clrscr();

    printf("Address of k&m in main(): %u%u",&k,&m);
    other(k,&m);

    return 0;
}

other(int k, int *m)
{
    printf("Address of k&m in other(): %u%u", &k,&m);
}

Output

 
Address of k&m in main(): 65524 65522
Address of k&m in other(): 65518 65522
