    No. Main is called by the executive that launches the program. One should never call main explicitly. The effects of doing so result in undefined operation.

    Yes a function can be called without calling the main or I would say a function can be executed before the main function is executed. Try running this program.
    Code:
    #include<iostream>
    using namespace std;
    
    int func()
    {
    	cout<<"In Func"<<endl;
    	return 10;
    }
    
    static int i = func();
    
    int main()
    {
    	cout<<"In Main"<<endl;
    	return 0;
    }
