尝试在Visual Studio 2022中构建和压缩我的一个文件，其中有5个C++文件。当我尝试运行其中一个文件时，所有文件都在那里，我得到了错误Unable to start program C:\Users\user\source\repos\CS102AS2_ZL\x64\Debug\CS102AS2_ZL.exe The system cannot find the file specified.它也会继续在控制台中说

[LNK2005] main already defined in t1.obj | File T2.obj | Line 1
[LNK1169] one or more multiply defined symbols found | File CS102AS2_ZL.exe | Line 1

我所有代码中的第一行是#include <iostream>
如果我尝试单独运行其中的一个，那么它很好，代码可以工作，但是当我尝试运行一个时，项目中有其他文件，那么它就会崩溃。

T1.CPP

#include <iostream>
#include <cmath>
using namespace std;

int main() {
    // Declaring Variables
    float a, b, c, x1, x2, discriminant, realPart, imaginaryPart;
    // User Input
    cout << "Enter coefficients a, b and c: ";
    cin >> a >> b >> c;
    discriminant = b * b - 4 * a * c;

    // Calculation for square root
    if (discriminant > 0) {
        x1 = (-b + sqrt(discriminant)) / (2 * a);
        x2 = (-b - sqrt(discriminant)) / (2 * a);

        // Outputs for square root
        cout << "Roots are real and unequal." << endl;
        cout << "x1 = " << x1 << endl;
        cout << "x2 = " << x2 << endl;
    }

    else if (discriminant == 0) {
        cout << "Roots are real and equal." << endl;
        x1 = -b / (2 * a);
        x2 = -b / (2 * a);
        cout << "x1 = " << x1 << " x2 = " << x2 << endl;
    }

    else {
        realPart = -b / (2 * a);
        imaginaryPart = sqrt(-discriminant) / (2 * a);
        cout << "Roots are imaginary." << endl;
        cout << "x1 = " << realPart << "+" << imaginaryPart << "i" << endl;
        cout << "x2 = " << realPart << "-" << imaginaryPart << "i" << endl;
    }

    return 0;
}

T2.CPP

#include <iostream>
using namespace std;

int main()
{
    // Declaring Variables
    int i, start, end;
    int chk = 0, j;
    bool is_prime = true;

    // User Input
    cout << "\nEnter starting number: ";
    cin >> start;
    cout << "\n" "Enter final number: ";
    cin >> end;
    cout << "Number divisible by 7 from " << start << " to " << end << endl;
    cout << "******************************\n";

    // Dividing by 7
    for (i = start; i < end + 1; i++)
    {
        if (i % 7 == 0)
        {
            // Divisible Output
            cout << " " << i;
        }
    }

    // Prime Numbers
    cout << "\n\nPrime Numbers";
    cout << "\n************* \n";

    // Prime Numbers Calculation
    for (start; start <= end; start++)
    {
        for (j = 2; j < start; j++)
        {
            if (start % j == 0)
            {
                chk++;
                break;
            }
        }

        // Prime Numbers Output
        if (chk == 0)
            cout << start << " ";
        chk = 0;
    }
    cout << endl;
    return 0;

}

我猜这段代码的错误是因为我的5个程序都有int main()，但据我所知，你在所有程序中都需要它？

我真的不知道该怎么做，因为这是我第一次制作一个项目，有5个不同的文件，因为我需要“压缩每个任务的整个项目文件夹，其中包含VC++文件，cpp文件，sln文件，调试文件夹等，并上传压缩的整个文件夹”
