题目:从键盘上输入五个整数分别存放到变量a,b,c,d,e中,将这五个数按升序排列并且输出。 思路:定义最大值,最小值函数。通过函数迭代,求出每组最小值,再通过对调法,将最小值一次置于变量a,b,c,d,e。即可 代码: #include using namespace std; int min(int); int max(int); int main() { int a, b, c, d, e,m, A, B, C, D, E; cout << “请分别输入5个整数” << endl; cin >> a >> b >> c >> d >> e; A = min(min(min(min(a, b), c), d), e);//确定第一位数字 if (b == A) m = a, a = b, b = m; else if (c == A) m = a, a = c, c = m; else if (d == A) m = a, a = d, d = m; else if (e == A) m = a, a = e, e = m; B = min(min(min(b, c), d), e);//确定第二位数字 if (c == B) m = b, b = c, c = m; else if (d == B) m = b, b = d, d = m; else if (e == B) m = b, b = e, e = m; C = min(min(c, d), e);//确定第三位数字 if (d == C) m =c, c= d, d = m; else if (e == C) m = c, c = e, e = m; D = min(d, e);//确定第四位数字 E = max(d, e);//确定第五位数字 cout << “升阶排序为:” << A << B << C << D << E << endl; return 0; } int min(int x, int y) { int f = 0; f= (x < y) ? x : y; return(f); } int max(int x, int y) { int g = 0; g = (x > y) ? x : y; return (g); }
运行结果: ps:本人是c++初学者,这是本人做作业时的一些思路分享,第一次发布,也希望大佬指正。
