C++ program to display pattern of alphabets

In this post, we will write a C++ program to display patterns of alphabets. the first user will enter the number between 1-19 and then the program will print the pattern of that equivalent character on the output screen.

C++ program to display patterns of alphabets.

#include<iostream>
#include<conio.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");
    int i,j,n;
    char ch;

    std::cout<<"Enter the number (1-19) you want the alphabets display = ";
    std::cin>>n;

    for(i=65;i<=65+n;i++)
    {
        for(j=1;j<=65+n-i;j++)
        {
                ch = i;
                gotoxy(i-64+i-64,j+5);
                std::cout<<ch<<std::endl;
        }
    }

    for(i=65+n;i>=65;i--)
        for(j=i;j<=65+n-1;j++)
        {
            ch = i;
            gotoxy(65+n-i+65+n-i+(n+n-2), 72-j+(n-2));
            std::cout<<ch<<std::endl;
        }

        getch();
        return 0;
}

Output

Enter the number(1-19) you want the alphabet display = 19
