C Exercises: Find the the Authomorphic numbers between 1 to 1000

C Numbers: Exercise-22 with Solution

Write a program in C to find the Authomorphic numbers between 1 and 1000.

Sample Solution:

C Code:

# include <stdio.h>
# include <stdlib.h>
# include <stdbool.h>

bool chkAutomor(int num1)
{
    int sqno = num1 * num1;
    while (num1 > 0)
    {
        if (num1 % 10 != sqno % 10)
            return false;
        num1 /= 10;
        sqno /= 10;
    }
    return true;
}
int main()
{
    int i;
  printf("\n\n Find the the Authomorphic numbers between 1 to 1000 \n");
  printf(" -------------------------------------------------------\n");
  printf(" The Authomorphic numbers are: ");
	for(i=1;i<=1000;i++)
	{
      if( chkAutomor(i))
         printf("%d ",i);
	}
 printf("\n");
}

Sample Output:

 The Authomorphic numbers are: 1 5 6 25 76 376 625
