hey guys, here is a code of pointer

  #include <iostream>

void test(int* i)
{
    *i = 2;
}

int main()
{
    int x = 3;
    test(&x);
    std::cout << x;
}

notice

test(&x);

that is need.
so, how do I make it into

test(x);

that is alot more convenient as a function.
this young beginner will be glad even if it's just a little help

Use a reference.

void test(int& i)
{
    i = 2;
}

int main()
{
    int x = 3;
    test(x);
    std::cout << x;
}
