What is the Out Put of these Programs in C ?? (With solution)

#include <stdio.h>
int main()
{
    float a = 5, b = 2  ;
    int c , d ;
    c= a / b;
    d= a / 2;
    printf (" %d %d \n", c , d);
    return 0 ;
}


ANS:-
Success time: 0 memory: 2052 signal:0
 2 2 



#include <stdio.h>
int main()
{
   printf ("nn \n\n nn\n");
    printf ("nn /n/n nn/n");
    return 0 ;
}

Ans
Success time: 0 memory: 2052 signal:0
nn 

 nn
nn /n/n nn/n



#include <stdio.h>
int main()
{
  int a,b;
  printf("Enter Values of a and b");
  scanf ("%d %d ", &a , &b );
  printf("a= %d b= %d ",a,b);
    return 0 ;
}

Ans 
Enter Values of a and b 
a= digit 1  b= digit 2
