    How to get this - some ideas please

    Write a program to produce the following output:
    ABCDEFGFEDCBA
    ABCDEF FEDCBA
    ABCDE EDCBA
    ABCD DCBA
    ABC CBA
    AB BA
    A A

    it should be like a pyramid
    my code is this:

    Code:
    #include <stdio.h>
    int main ()
    {
     char a,b,c;
          for (b=65;b<=70;b++)
          printf ("%c", b);
          for(a=70;a>64;a--)
          printf ("%c", a);
          printf ("\n");
    
          for (b=65;b<=69;b++)
          printf ("%c", b);
          printf ("\n");
    
          for (b=65;b<=68;b++)
          printf ("%c", b);
          printf ("\n");
    
          for (b=65;b<=67;b++)
          printf ("%c", b);
          printf ("\n");
    
          for (b=65;b<=66;b++)
          printf ("%c", b);
          printf ("\n");
    
          for (b=65;b<=65;b++)
          printf ("%c", b);
          printf("\n");
    }

    Code:
    printf("     ");
    printf("%c",73);
    printf(" wonder where?\n");
    An experiment.

    i used printf("\n"); to get the variables printed in next line after for loop executes so each time i execute a for loop i have to print out the it in new line so that the ABCDEFG will become ABCDEF next line like this untill i get down to letter A. I also want to ask y you used printf("%c",73) can you please explain to me so that i can understand bit much about it.Thanks in advance.

    b<=70
    b<=69
    Consider another loop, which counts backwards.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
