HW 4

CS156 HW4: Pangrams!                

Description                

The world seems to be filled with tired canines and springy vulpines!                 

For this assignment, you will write a program called pan.c that searches for pangrams, sentences that contain all 26 letters in the alphabet. It will search the file sentences, which will be assumed to contain one sentence per line. If the line is a pangram, display it, with its line number. At the end, display how many pangrams were found.                 

Sample Run                

Text like this is typed by the user.                 

%” is the shell prompt and not a part of your program.                 

    % cat sentences

    Pack my box with five dozen liquor jugs.

    % c11 -Wall pan.c 
    % ./a.out

    3: Pack my box with five dozen liquor jugs.
    4: YbOvgEznjLcpisKrauqmXTDwFh
    7: The five boxing wizards jump quickly
    4 pangrams found.
    % mv sentences sentences.save
    % date >sentences
    % ./a.out
    No pangrams found.

If you encounter “STACK FRAME LINK OVERFLOW”, then try this:

    export STACK_FRAME_LINK_OVERRIDE=ffff-ad921d60486366258809553a3db49a4a
