In this tutorial, we are going to write a C Program to show call-by-value in C Programming with practical program code and step-by-step full complete explanation.
C Program to show call by value
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,swap();
clrscr();
a=5;
b=10;
printf("Value of a=%d & value of b=%d before swap ",a,b);
swap(a,b);
printf("nvalue of a=%d & b=%d after swap",a,b);
getch();
}
int swap(int x, int y)
{
int temp;
temp = x;
x = y;
y = temp;
}
Output
Value of a=5 & value of b=10 before swap Value of a=5 & b=10 after swap
