c++程序出现exit code -1073740940 (0xC0000374)
一道动态规划的算法题.
dp是我用new关键字分配的一个整形数组用来记录转移量,在程序51行使用"delete []dp;"去释放内存
出现exit code -1073740940 (0xC0000374)的错误,用的是gnu++11
#include <iostream>
#include <vector>
using namespace std;
vector<int> get_pisor(int num)
{
vector<int> vec;
for (int i = 2; i < num; ++i) {
if (num % i == 0) {
vec.push_back(i);
}
}
return vec;
}
int max_step(int v_start, int v_end)
{
if (v_start >= v_end) {
return -1;
}
int start = v_start;
int end = v_end;
int rslt;
int *dp = new int[end - start + 1];
//初始化所有dp内的元素
for (int i = start; i <= end; ++i) {
dp[i] = 0;
}
vector<int> vec;
for (int i = start; i <= end; ++i) {
vec = get_pisor(i);
//如果向量为空,说明在该步不存在约数,无法到达end
if (vec.empty()) {
dp[i] = 0;
} else {
vector<int>::iterator iter;
for (iter = vec.begin(); iter != vec.end(); ++iter) {
if (dp[i + (*iter)] == 0) {
dp[i + (*iter)] = dp[i] + 1;
} else {
dp[i + (*iter)] = (dp[i] + 1) > dp[i + (*iter)] ? dp[i + (*iter)] : dp[i] + 1;
}
}
vec.clear();
}
}
rslt = dp[v_end];
delete []dp;
return rslt;
}
int main()
{
int rslt = max_step(4, 24);
cout<<rslt<<endl;
}按理说我动态申请的数组在使用最后delete应该是没问题的吧,但不知道为什么会出现这个错误,还请指教
