C++ program to convert the small case letters to upper case letters

#include<iostream>
#include<conio.h>
#include<string.h>
#include<windows.h>

BOOL gotoxy(const WORD x, const WORD y) {
    COORD xy;
    xy.X = x;
    xy.Y = y;
    return SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), xy);
}

int main()
{
   system("cls");

    char ch;
    char arr[5];
    int i=1,j=1,c=1;

    arr[i] = getch();

    while(arr[i] != 27)
    {
        gotoxy(j,c);
        std::cout<<arr[i];
        i++;
        arr[i] = arr[i-1];
        int k = arr[i]-32;
        i--;

        arr[i] = getch();
        gotoxy(j,c);
        std::cout<<char(k);
        j++;

        if(j==80)
        {
            j = 1;
            c = c+1;
        }
    }

    return 0;
}
