数学趣题——具有特殊性质的数

1、题目

2、源码

[code] #include <stdio.h>

void func()

{

 int a, b, c, d;

 for(a = 1; a <= 9; a++)

 for(b = 0; b <= 9; b++)

 for(c = 0; c <= 9; c++)

 for(d = 0; d <= 9; d++)

{

 if(a * 1000 + b * 100 + c * 10 + d == ((a * 10 + b) + (c * 10 + d))* ((a * 10 + b) + (c * 10 + d)))

 printf("%d%d%d%d\t", a, b, c, d);

}

}

int main()

{

 printf("There are following numbers according with the condition\n");

 func();

 return 0;

}
