本文实例讲述了C++实现从数组中同时取出最大最小元素的方法。分享给大家供大家参考，具体如下：
算法思想：先相邻两个两个比较，较大的放入数组max[],较小的放入数组min[],然后从max[]数组求出最大，min[]数组求出最小即可。
比较n+[(n+1)/2] =1.5n次

#include <iostream>#define n 11#define m ((n+1)/2)using namespace std;void main(void){ int num[] = {11,2,3,4,6,5,7,8,9,10,20}; //int n = sizeof(num)/sizeof(num[0]); //int m = (n+1)/2; int max[m] , min[m]; int k = 0, j = 0; if(n/2 != 0) max[m-1] = min[m-1] = num[n-1]; for (int i=0; i < n-1; i = i+2) { if (num[i] >= num[i+1]) { max[j++] = num[i]; min[k++] = num[i+1]; } else { max[j++] = num[i+1]; min[k++] = num[i]; } } for( i=0; i< m; i++) { cout << "max[" << i << "] = " << max[i] << "\t"; cout << "min[" << i << "] = " << min[i] <<endl; } int MAX = max[0]; int MIN = min[0]; for ( j = 1; j < m; j++) { if (max[j] > MAX) MAX = max[j]; if (min[j] < MIN) MIN = min[j]; } cout << "MAX = " << MAX << ", MIN = " << MIN <<endl;} |
希望本文所述对大家C++程序设计有所帮助。
