swap_int(address variable 1,address variable 2)

Swap takes addresses of two Integer type variables as arguments and swap value of them.

Syntax:

swap_int(address of variable 1 , address of variable 2);

Examples:

#include<cquery.h>
main()
{
int var1 = 1 , var2 = 3;
swap_int(&var1,&var2); //now var1 = 3 and var2 = 1
printf("var1 = %d , var2 = %d ",var1,var2);
}

Order of arguments doesn't matter as you can swap them as also

#include<cquery.h>
main()
{
int var1 = 1 , var2 = 3;
swap_int(&var2,&var1); //now var1 = 3 and var2 = 1
printf("var1 = %d , var2 = %d ",var1,var2);
}

But remember arguments should be direct address or you can use pointers as

#include<cquery.h>
main()
{
int var1 = 1 , var2 = 3;
int *a,*b;
a = &var1;
b = &var2;
swap_int(a,b); //now var1 = 3 and var2 = 1
printf("var1 = %d , var2 = %d ",var1,var2);
}
