Print Number of Perfect Squares Between two numbers

Write a program to find the number of perfect squares between given two numbers A and B (both inclusive). A number is called a perfect square if it can be written as x*x for some integer x.

Example 1:

Input: 3 17

Output: 3

Solution.

#include<stdio.h>

int main()

{

  int a, b;

scanf("%d%d", &a, &b);

 

int count=0;

int i, h;

for(i=1; i<=b; i++)

{

h=i*i;

if((a<=h)&&(b>=h))

count++;

}

  printf("%d", count);

  return 0;

}
