How to output three numbers according to size in C language?

Analysis and implementation of outputting three numbers by size in C language:

1. Analysis:The sorting of three numbers only requires three comparisons.

First, let these three numbers be a, b, and c respectively.

(1) Compare a with b, if a > b, exchange the values of a and b, compare a with c,

(2) If a > c, exchange a and c Compare the value b with c,

(3) If b > c, exchange the values of b and c

After three rounds of comparison, output a, b, c in order of size arranged.

2. Implementation:

#include  int main() { int a; int b; int c; int t; // 临时变量用于交换两变量的值 printf("请输入a、b、c的值，中间用空格隔开："); scanf("%d%d%d", &a, &b, &c); if (a > b) { t = a; a = b; b = t; } if (a > c) { t = a; a = c; c = t; } if (b > c) { t = b; b = c; c = t; } printf("排序后a、b、c的值为%d、%d、%d", a, b, c); }

3. Running result:

请输入a、b、c的值，中间用空格隔开：4 1 7 排序后a、b、c的值为1、4、7
