By reference:


              
12345678910

            
void incValue(int &x) {
    x++;
}

int main() {
    int x = 1;
    incValue(x);
&nbsp;&nbsp;&nbsp;&nbsp;cout << x; 
&nbsp;&nbsp;&nbsp;&nbsp;return 0;
}
copy

Here we change x as the function works with the address (reference) of this variable. It can be useful in case you need to change the value of the parameters.
