c++ - 如何在 mac 上使用 Ifstream codeblocks？

Question

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ifstream inFile;
    inFile.open("test.txt");

    int foo;
    string sFoo;

    inFile >> sFoo;
    inFile >> foo;

    cout << "the name is " << sFoo << endl;
    cout << "the first number is "  << foo << endl;

    inFile >> foo;
    cout << "the second number is " << foo << endl;

    cout << "Hello World!";
    return 0;
}

我试过将我的文本文件放在同一个文件夹中。但是，由于某种原因，它无法读取文本文件。请有人告诉我在 macbook 上的代码块中要做什么才能实现这一目标!

您必须写下文件的完整绝对路径，而不是相对路径。我已经回答了同样的问题here .

#include <iostream>
#include <fstream>

using namespace std;

int main()
{
    ifstream inFile;
    inFile.open("/Users/user/Desktop/test.txt");
    if(inFile){
        int foo;

        string sFoo;

        inFile >> sFoo;
        inFile >> foo;

        cout << "the name is " << sFoo << endl;
        cout << "the first number is "  << foo << endl;

        inFile >> foo;
        cout << "the second number is " << foo << endl;

        cout << "Hello World!"; 
        inFile.close();

    }else{
        cout<<"unable to open file"<<endl;
    }
    return 0;
}
