cant run a different main function in c++

Question

Hello, i have a project with 2 cpp files, the c++.cpp file and the ciclos.cpp file, c++.cpp file has a main function and ciclos.cpp file has another main function named main_2, im trying to run main_2 function in the ciclos.cpp file but visual studio only runs the main function in the c++.cpp file.

Hi, @Thomas Timana

If you want to run main_2 instead of main as the entry point, you need to set the entry point:

//turn off /RTC*
#pragma runtime_checks("", off)
//add entry point
#pragma comment(linker, "/ENTRY:main_2")
//add runtime lib
#pragma comment(lib,"ucrtd.lib")
#pragma comment(lib,"vcruntimed.lib")

Console sample:

#include<iostream>
// turn off /RTC*
#pragma runtime_checks("", off)
#pragma comment(linker, "/ENTRY:main_2")
#pragma comment(lib,"ucrtd.lib")
#pragma comment(lib,"vcruntimed.lib")
int  main_2()
{
    std::cout << "hello main 2";
    return 0;;
}
int main()
{
    std::cout << "hello main 1 ";
    return 0;
}
