#include <stdlib.h>

int main()

{

    int X,y,temp;

    printf("Enter number for the first variable\n");

    scanf("%d",&X);

    printf("enter number for the second variable\n");

    scanf("%d",&y);

    temp=X;

    X=y;

    y=temp;

    printf("first variable value %d \n",X);

    printf("second variable value %d \n",y);

    return 0;

}

    

programming C (student name with age)

    age=2020-b_year;

    printf("student name is %s \n",name);

    printf("student age is %d \n",age);

    return 0;

}

    printf("total is %d \n",x+y);

    return 0;

}

    

programming C(two numbers average)

 Numbers average

#include <stdio.h>
