C ++进程终止于状态-1073741510（0分钟，2秒） [英] C++ Process terminated with status -1073741510 (0 minute(s), 2 second(s))

问题描述

执行exe后，我收到此错误：

进程以状态-1073741510（0分钟，2秒）终止

我应该为long变量设置一个限制吗？我在编译后收到0条警告

以下是代码：

  #include< iostream> 
 #include< fstream> 
 //＃define long long 100000000; 
 //＃define int 1000; 
 
 using namespace std; 
 void test1（）; 
 void test2（）; 
 void test3（）; 
 int main（）
 {
 int p，n; 
 // long z; 
 long sir [2 * n]; 
 std :: ifstream file; 
 file.open（input.txt）; 
文件>> p; 
 file>> n; 
 for（int i = 0; i <（2 * n）; i ++）{
 file>> sir [i]; 
} 
 file.close（）; 
 if（p == 1）test1（）; 
 else if（p == 2）test2（）; 
 else test3（）; 
 return 0; 
} 
 void test1（）{
 cout<< 1; // sir [2]; 
} 
 void test2（）{
 cout<< d; 
} 
 void test3（）{
 cout<< d; 
} 
  

解决方案

$ c> n 之前使用 long sir [2 * n]; 。这个测量你使用一个垃圾大小声明数组，所以现在你有一个垃圾数组。

由于 long sir [2 * n];

code>是一个可变长度数组，不是标准的我建议您使用 std :: vector ，并在从文件中读取它后设置它的大小。像下面这样应该工作

  file.open（input.txt）; 
文件>> p; 
 file>> n; 
 std :: vector< long> sir（n）; 
  

如果不能使用向量，那么你可以使用一个指针并创建 $ >

$ ）;
file>> p;
file>> n;
long * sir = new long [2 * n];


你必须记住使用 delete [] sir; 你完成后，你会得到一个内存泄漏。

After I execute the exe I get this error :

Process terminated with status -1073741510 (0 minute(s), 2 second(s))

Should I set a limit to long variables ? I get 0 warnings after compiling

Here is the code :

#include <iostream>
#include <fstream>
//#define long long 100000000;
//#define int 1000;

using namespace std;
void test1();
void test2();
void test3();
int main()
{
    int p,n;
   // long z;
    long sir[2*n] ;
    std::ifstream file;
    file.open("input.txt");
    file >> p;
    file >>n;
    for (int i=0;i< (2*n);i++){
        file >> sir[i];
    }
    file.close();
    if (p==1)test1();
    else if(p==2)test2();
    else test3();
    return 0;
}
void test1(){
    cout << 1;//sir[2];
}
void test2(){
    cout << "d";
}
void test3(){
    cout << "d";
}

解决方案

You never initialized n before you used in long sir[2*n] ;. This meas you use a garbage size do declare the array so now you have a garbage array. Any use of that array is going to be undefined behavior and the cause of your problem.

Since long sir[2*n] ; is a variable length array and not standard I suggest you use a std::vector and set its size after you read it in from the file. Something like the following should work

file.open("input.txt");
file >> p;
file >>n;
std::vector<long> sir(n);

If you can't use a vector then you can you a pointer and create the array with new after you read the size like

file.open("input.txt");
file >> p;
file >>n;
long * sir = new long[2*n];

You do have to remember to use delete [] sir; after you are done with it so you do get a memory leak.
