what is call by reference code example
Example 1: , Call by Reference,
/* function definition to swap the values */
void swap(int *x, int *y) {
int temp;
temp = *x; /* save the value at address x */
*x = *y; /* put y into x */
*y = temp; /* put temp into y */
return;
}
Example 2: calling by reference c++
int main() {
int b = 1;
fun(&b);
// now b = 10;
return 0;
}
Example 3: call by reference
//Call By Reference
#include<stdio.h>
void function(int *, int *); //function declaration
int main()
{
int a,b;
printf("Enter first number: ");
scanf("%d",&a);
printf("Enter second number: ");
scanf("%d",&b);
function(&a,&b); //passing the address of both the variables( CALL BY REFERENCE)
}
void function(int *p,int *q) //function defination
{
printf("printing variables from function a=%d b=%d",*p,*q);
}
//code by Dungriyal..
Example 4: what is call by value and call by reference
/* function definition to swap the values */
void swap(int *x, int *y) {
int temp;
temp = *x; /* save the value at address x */
*x = *y; /* put y into x */
*y = temp; /* put temp into y */
return;
}
