Question

What they are asking to do it to print:

F
FE
FED
FEDC
FEDCB
FEDCBA

I was able to print:

F
FF
FFF
FFFF
FFFFF

with this code:

int main()
{
    int count, count2;

    char letterToPrint = 'F';

    for (count = 0; count < 5; count++)
    {
        for (count2 = 0; count2 <= count; count2++)
        {
            printf("%c", letterToPrint);
        }
        printf("\n");
    }
}

Is there something I can add in the second for loop to print the previous letter and then decrement it, or does this take another loop?

Answer 1

You just need to change the value of letterToPrint in your inner loop and reset it at the start of the outer loop:

int main()
{
    int count, count2;
    for (count = 0; count < 5; count++)
    {
        char letterToPrint = 'F'; // MOVED
        for (count2 = 0; count2 <= count; count2++)
        {
            printf("%c", letterToPrint--);
            //                        ^^
        }
        printf("\n");
    }
}
