问题描述

DEV-C报错 Process exited after 4.03 seconds with return value 3221225725

原因
数组定义的容量太大 - 五十万起步的样子
而且每次循环都会再定义一次，导致缓存区溢出

解决办法：

办法：数组定义在主函数外面 作为全局变量

#include<bits/stdc++.h>
#define num 10000
#define cmp <
using namespace std;long a[1500000]; // 一百五十万int main()
{srand(time(NULL));clock_t start, end; double Total_time;long length; long l = 600000;long b[10];for(int i = 0;i<10;i++) {b[i] = l;l = l+100000;}for(l=0;l<10;l++){start = clock();int k;length = b[l];for(k = 0;k<length;k++){a[k] = rand()%num;}int i, j, temp;cout << "length = " << length <<  endl;cout << "开始直接插入排序(for)  ";for(i = 1; i < length; i++){temp = a[i];for(j = i-1; j >= 0; j--){if(temp cmp a[j])a[j + 1] = a[j];elsebreak;}a[j + 1] = temp;}cout << "排序完成！ ";end = clock();Total_time = (double)(end - start) / CLOCKS_PER_SEC;cout << "用时 = " << Total_time << endl <<endl;start = end;}system("pause"); return 0;
