Swapping of two numbers.....

Question

Can any of you give me the source code for swapping of two numbers using call by value in C !!!!!😊

Answer 1

#include <stdio.h>

int swap(int* a, int* b){
int temp = *a;
*a = *b;
*b = temp;
}

int main() {
int n1 = 4;
int n2 = 5;
printf( "First: %d\nSecond: %d", n1, n2) ;
swap(&n1,&n2);
printf("After swap:\n" );
printf( "First: %d\nSecond: %d", n1, n2) ;
return 0;
}

Answer 2

And if you want without function:

#include <stdio.h>

int main() {
int n1 = 4;
int n2 = 5;
int temp;
printf( "First: %d\nSecond: %d", n1, n2) ;
temp = n1;
n1 = n2;
n2 = temp;
printf("After swap:\n" );
printf( "First: %d\nSecond: %d", n1, n2) ;
return 0;
}
