Answer 1

Something is screwy here. When I see /tmp/ccEcsWOr.o: and (.text+0x21) I expect to see:



collect2: ld returned 1 exit status



This is a linker error not a syntax error. In essence that means that the preprocessor found a header file which contains getint() and set aside space to link to it in libc (which is the standard C library always linked to when you #include files from stdio.h or stdlib.h which stdio.h calls). Either you called getint() in a way which made the compiler set aside memory the wrong way, or there is something wrong with the installation of your libc library. In either case you shouldn't ask here, you should ask your instructor or someone in the computer lab.

Answer 2

It doesn't work because "getint()" isn't a defined function. You'll need to write your own function for that :), or, look up "scanf".

Answer 3

intstead of details.number = getint();



i would use scanf("%d",&detail.number);



i haven't seen getint() before that looks like a java method,
