halp C++

// EX4_3.CPP
//Initialise a string, and then use a loop function to change every letter to uppercase
#include<iostream>
using namespace std;
int main()
{
    const int MAX = 80;            // maxximum length of string
    char buffer [MAX];            // input buffer
    char* pbuffer = buffer;        // pointer to array buffer
    int i = 0;


        cout << endl
        << "Enter a string of lowercase letters less than " << MAX << "characters:"
        << endl;

    cin.getline(buffer, MAX, '\n');        //read string until \n

    while(*pbuffer)                        // continue until /0
            pbuffer++;

    for(i = 1; i <= *pbuffer; i++)
        buffer[i]-32 = buffer[i];

    cout << "CRUISE CONTROL = " << buffer << " LOLZ"
        << endl;
    return 0;
}


WHAT THE FUUUUUCK do i do to incriment every character in the array buffer to uppercase? its ASCII so i just subtract 32,
right?

//Initialise a string

Programming is done in AMERICAN English, thank you.
