程序描述

一个数的平方是该数乘以自身。

一个平方数或完全平方是一个整数，它是一个整数的平方；

完全平方数是整数的平方。

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

这里是从1到100的所有完全平方数的平方根。

√1 = 1 since 12 = 1
√4 = 2 since 22 = 4
√9 = 3 since 32 = 9
√16 = 4 since 42 = 16
√25 = 5 since 52 = 25
√36 = 6 since 62 = 36
√49 = 7 since 72 = 49
√64 = 8 since 82 = 64
√81 = 9 since 92 = 81
√100 = 10 since 102 = 100

A non-perfect square is every number that is not the result of squaring an integer with itself.

The below numbers are non-perfect square numbers

2,3,5,6,7,8,10,11,12,13,14,15,17,18,19,20,21,22,23,24,26 etc…

算法

Check all numbers from 1 to the user specified number.
Check if it is perfect square or not.
If not a perfect square, print the Non Perfect Square Number.

Example

示例

/* Program to print non square numbers */
#include <stdio.h>
#include <math.h>
int main() {
   int number,i,x;
   int times = 0;
   clrscr();
   printf("Print the Non Square Numbers till:");
   scanf("%d", &number);
   printf("The Non Squre Numbers are:");
   printf("
");
   for(i = 1;times<number;i++,times++){
      x = sqrt(i);
      if(i!=x*x){
         printf("%dt", i);
      }
   }
   getch();
   return 0;
}
