Thread: C Compiling error

I am using a GCC compiler and getting the following errors:
prog1.c: In function `main':
prog1.c:57: error: missing terminating " character
prog1.c:58: error: syntax error before ':' token
prog1.c:58: error: missing terminating " character

I have counted all my

Code:

{ and }

to ensure there was the same number but still am stumped. thanks in advance all!

Please provide all of the compiler errors. Copy-paste them exactly, including line numbers. It also wouldn't hurt if you provided the exact command you used to compile. E.g.

Code:

$ gcc -Wall -g -std=c99 -pedantic  -lm -lpthread -lefence  fifo.c   -o fifo
fifo.c: In function ‘main’:
fifo.c:12: warning: implicit declaration of function ‘clrscr’
fifo.c:58: warning: implicit declaration of function ‘exit’
fifo.c:58: warning: incompatible implicit declaration of built-in function ‘exit’
/tmp/cc3srhKe.o: In function `main':
/home/tyco/sandbox/cprogramming/fifo.c:12: undefined reference to `clrscr'
collect2: ld returned 1 exit status
make: *** [fifo] Error 1

Hmm...I don't get any such error, as you can see from the output I provided in post #3. Also, I think your line numbers in what you posted are a bit different from the code you posted.

Are lines 57-58 in your program the following two?

Code:

printf("\n\n\tDo u want to continue IF YES PRESS 1\n\n\tIF NO PRESS 0 : ");
scanf("%d", &YN);

Look for a missing " somewhere (an editor that provides syntax highlighting is indespensible for things like this). Alternatively, copy-paste the code form the forum here into your editor, save the file and try recompiling. The code here seems to be fine (except for using the non-standard clrscr, and you need to #include <stdlib.h> if you want to use the exit function).

Those are the two lines my compiler is counting as 57 and 58

Still getting that error! Ugh!

OK now i have C-Free to test (which is WAY nicer than darn school way) but i am getting a 'clrscr" was not declared in this scope. I have added:

Code:

#include <stdlib.h> 
#include <conio.h>

got it! Took out the <conio.h> and put in:
system("cls"); where the clrscr was
