我正在MacOS上使用VS代码调试以下try C ++程序。它需要用户输入。只是需要两个数字作为输入并返回数字列表作为输出。这是我的launch.json

"version": "0.2.0",
"configurations": [
{
"name": "(lldb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/hello",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": true,
"MIMode": "lldb"
}
]
}
当我按F5键时,确实确实启动了一个外部终端窗口,但是它不执行输出文件“ hello”,它只是在我的主文件夹〜中显示常规提示。如果我只是简单地运行文件,那么一切都会正常运行。 因为它很简单,所以我将发布要调试的确切代码作为示例。
#include <iostream>
using namespace std;
class Calculator
{
private:
/* data */
public:
Calculator(/* args */) {}
~Calculator() {}
void PrimeGenerator(int, int);
};
int main(int argc, char *argv[])
{
cout << "Please enter two numbers: " << endl;
int x, y;
cin >> x >> y;
Calculator c;
c.PrimeGenerator(x,y);
cin.ignore();
cin.get();
return 0;
}
void Calculator::PrimeGenerator(int x, int y)
{
for (int i = x; i < y; i++)
{
bool prime = true;
for (int j = 2; j * j <= i; j++)
{
if (i % j != 0)
{
prime = false;
break;
}
}
if (prime==true) {
cout << i << " ";
}
}
}
答案 0 :(得分:5)
似乎代码本身没有问题。
您对外部控制台有硬性要求吗?如果没有,可以在终端中手动运行该应用程序,然后附加:

"type": "cppdbg",
