C语言：使用不同方法生成三位数排列组合（无循环）

#include <stdio.h> int main() { int a,b,c; printf('请输入三个不同的数字:'); scanf("%d %d %d",&a, &b, &c); if (a == b || a == c || b == c){ printf('输入的数字有相同的数 '); return 0; } int num1 = a100 + b10 + c; int num2 = a100 + c10 + b; int num3 = b100 + a10 + c; int num4 = b100 + c10 + a; int num5 = c100 + b10 + a; int num6 = c100 + a10 + b; printf ('由这三个数字组成的三位数如下: '); printf ("%d ", num1); printf ("%d ", num2); printf ("%d ", num3); printf ("%d ", num4); printf ("%d ", num5); printf ("%d ", num6); return 0; }
