假设需要打印的数组为int类型，数组名为Array，Dim1为数组的行，Dim2为数组的列。
int i,j//临时变量for(i = 0 i < Dim1 i++)//外层循环遍历行
for(j = 0 j < Dim2 j++)//内层循环遍历列
{
printf("%d ",Array[i][j])//访问数组元素并打印
}
打印数组时（无论几维）都要注意数组下标从0开始，除非刻意放弃下标为0的元素，多存一个元素，此时for循环范围则可从1开始到数组长度。
N个元素中取出M个元素的所有排列#include <stdio.h>#define MAX 10int used[MAX]int result[MAX]int M, Nvoid print() { int i for(i = 0i <Mi++) printf("%d ", result[i])printf("\n")}void Perm(int step) { int iif (step == M) print()elsefor(i = 0i <Ni++)if (!used[i]) {used[i] = 1 result[step] = i + 1 Perm(step + 1) used[i] = 0 }}main() {scanf("%d %d", &M, &N) Perm(0)}
N个元素中取出M个元素的所有组合
