Program 

#include<stdio.h>
void main()
{
  int num,f,m;
  printf("\nEnter a number ");
  scanf("%d",&num);
  if(num%5==0)
  {
   f=1;
  }
    if(num%7==0)
  {
    m=1;
  }
if(f==1 && m==1)
 {
printf("\nThe number %d is divisible by 5 and 7",num);
 }    
else if(f==1)
 {
printf("\nThe number %d is divisible by 5 but not by 7",num);
}
else if(m==1)
{
printf("\nThe number %d is divisible by 7 but not by 5",num);
}    
else
{
    printf("\nThe number %d is neither divisible by 5 nor by 7",num);
}
}

Output

Enter a number 456

The number 456 is neither  divisible by 5 nor by 7
