2 output functions in C-CodePudding

so i tried making 2 functions and want to display both outputs and im new to C how do i fix this issue?

Code:

#include <iostream>

namespace first{
    int x = 1;
}
namespace second{
    int x = 2;
}
int main() {

using namespace first;


int x = 0;


std::cout << x << '\n';
std::cout << first::x << '\n';
std::cout << second::x << '\n';

return 0;
}

int lol() {

using namespace std;
using std::cout;

string lolipop = "hello world";

cout << lolipop << '\n';

return 0;

}

i want to display both outputs including hello world and the variables, variable are getting displayed in the output but not the second function the lol one.

CodePudding user response：

You have to call lol function from main.

CodePudding user response：

You need to call lol().

Example:

int lol(); // forward declaration

int main() {
    using namespace first;

    int x = 0;

    std::cout << x << '\n';
    std::cout << first::x << '\n';
    std::cout << second::x << '\n';
    
    lol();                             // calling lol

    return 0;
}
