:/ C language again
« on: April 28, 2017, 10:03:22 am »


Any idea why for is not stopping ? even after it reaches i = 7 :/ [Seems like I found a way to fix this problem as well, sorry for wasting your time lads :/ ]

another question is, why is it printing 3 and 4 at the same time, instead of waiting for scanf to finish its job ? [ Fixed this problem by having a space before %c, changed from scanf("%c"&c); ---------> scanf(" %c" &c);

Please show the full code, else nobody can help you: https://pastebin.com/

You might want to disable input/output buffering. Add the following lines to your code directly under main:
Code: [Select]
setbuf(stdout, NULL);
setbuf(stdin, NULL);

Sounds like a wrong pointer somewhere. Couldn't spot it by flying over your code. I'd recommend debugging it: https://www.gnu.org/software/gdb/ I've used gdb before for uni homeworks and found it useful.

Don't understand these things, but you probably want to add this (took your code from choice 3):
Code: [Select]
printMenu();
printf("Please enter your choice: ");
scanf("%d" ,&choice);After line 87
Plus add the same thing after line 83

Currently if you enter 4 or 5 then the do-while loop will keep looping without giving you an option to pick something else. So it'll just loop back to 4 or 5.

That's actually what caused the problem ;P
it kept checking if ' Check ' was on 5 all the time which it returns true then goin all over the function again ;)


Thanks lads, I really appreciate it


I'll lock it for now as it has been solved, danks ;P
