im kind of a beginner at this and my teacher expects a lot from us so i have sarted something but im having trouble printing the letters lets say the user types in p i can conver the small p toa capital p but i can get it to print like
A
B
C
D all the way to p

#include <stdio.h>
    // continue.c

int main(void)
{
    char letter;
        int rows;
    char spaces;
    spaces=' ';
    

    printf("Type a single lowercase letter and press enter:");
    scanf("%c",&letter);
        if((letter<96) || (letter>122));
        {
            printf("That is not a lowercase letter enter a lowercase letter");
            
        }
        else
        {
            letter=letter-32;
            for(letter='A'; letter<96 || letter>122; letter++)
            {

            for(spaces=0; spaces < 0; spaces++);    
            {
                spaces=letter-1;
                putchar(spaces);
                spaces++;
            }

            for(rows=0; rows < 0; rows++)
            {
                rows=letter-'A';
                putchar(rows);
                rows++;
            }
        }
    
    return 0;
}

i also know that using the spaces are generated by the letter-a. lets say the user types in letter e the ascii value is 101 - letter a which is accii value 97 that would create the number of spaces which is 4

else
    {
        letter=letter-32;
        for(letter='A'; letter<96 || letter>122; letter++)
        {

Your for statement just destroyed the letter you typed in.

Also, it would be better to use getchar() instead of scanf() to read in a character. getchar() is designed to read a char whereas scanf() has to process the "%c" to find out you want to read a character then do what getchar() already does.

Stop attaching short programs, please. It's better to embed the code in your post when you can and attach only when the code is far too long to be put in a post.
