which would be helpful how?

Code:

int myLeetVar = 1;

void setLeet(int leet)
{
    leet = 1337;
}

int main()
{
    setLeet(myLeetVar);
    cout<<myLeetVar;
}

outputs: 1

Code:

int myLeetVar = 1;

void setLeet(int *leet)
{
    *leet = 1337;
}

int main()
{
    setLeet(myLeetVar);
    cout<<myLeetVar;
}

outputs: 1337

Useful for game classes etc

Ok thank you, I understand it now... Pointers are helpful when used in functions to change the value of a variable outside of the function?
