c++随机选出4个元素排列组合
#include #include using namespace std;void FillArr(int* pnArr, int *pnDesArr, int i){//取0-10之间的一个随机数int m = rand() % 11;int temp = pnArr[m];bool bIsRepeat = false;//判断随机取得的一个数是否与前面取得的数重复for (int j = 0; j < i; ++j){if(pnDesArr[j] == temp){bIsRepeat = true;break;}}//如果重复则重新随机取一个数if (bIsRepeat){FillArr(pnArr, pnDesArr, i);}//如果不重复就将这个随机取得的数填充到目标数组中else{pnDesArr[i] = temp;}}int main(){int nArr[11] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};int nDesArr[9] = {0, 0, 0, 0, 0, 0, 0, 0, 0};srand((unsigned)time(NULL));for (int i = 0; i < 9; ++i){FillArr(nArr, nDesArr, i);cout<<nDesArr[i]<<endl;}getchar();return 0;}

C\/C++语言 从33个数中选6个排列组合
组合:从n个不同元素中取r个不重复的元素组成一个子集,而不考虑其元素的顺序,称为从n个中取r个的无重组合,例如OR = {1,2,3,4}, n = 4, r = 3则无重组合为:{1,2,3}; {1,2,4}; {1,3,4}; {2,3,4}.include <stdio.h> include <stdlib.h> include <iostream.h> in...

如果需要显示更多数字的组合可能,可以选择修改list[]数组中元素的个数即可。\/ include <stdio.h>#include <conio.h> int n = 0;void swap(int *a, int *b){ int m;m = *a;a = *b;b = m;} void perm(int list[], int k, int m, FILE *fp){ int i;if(k > m){ for(i...
