Automorphic Number or Not | C Program
Automorphic Number in C
In this program, we have to find the number is an Automorphic number or not using C programming. Basically, automorphic number is a number whose square ends with the same digits as number itself.
Automorphic Number in C Programming
Example:
5 =(5)2 = 25 6 = (6)2 = 36 25 = (25)2 = 625 76=(76)2 = 5776 376 = (376)2 = 141376 890625 = (890625)2 = 793212890625
These numbers are the automorphic numbers.
C Program:-
Run
#include <stdio.h>
int checkAutomorphic(int num){
int square = num * num;
while(num != 0)
{
// means not automorphic number
if(num % 10 != square % 10){
return 0;
}
// reduce down numbers
num /= 10;
square /= 10;
}
// if reaches here means automorphic number
return 1;
}
int main ()
{
int num = 376, square = num * num ;
if(checkAutomorphic(num))
printf("Num : %d, Square: %d - Automorphic Number",num, square);
else
printf("Num : %d, Square: %d - Not Automorphic Number",num, square);
}
// Time complexity: O(N)
// Space complexity: O(1)Output:-
Num : 376, Square: 141376 - Automorphic Number
