I need it because,I. Don't have knowledge of makefile and also,it

Then, as I said, learn to program first. Make and Makefiles are quasi-standard for C compiling. Also, as I said many times, learning programming on Windows is almost useless for programming on other systems other than Windows, because Windows does stuff in a non-standard way.

Those who say "learn to program on Windows first" are stupid.

is there any way i can see my errors other than a screenshot before it exits

Frankly, that program needed to be rewritten. It was overly complex, you didn't need any of those structs, strcats, and arrays. Pretty much loops, if statements, and printf are all you need.

I've given you a head start with the rewrite, you just have to finish questions 3-10.

[varun]

its cool......i mean defining printf and making padinput and scoring is a cool idea.
about structure part.... i had to do it because in the pc version, my program used to randomly generate the questions...and in psp one i had no idea to randomize things. Its very nice of you to do that ..Finally i can program in psp...

btw..ur awatar reminds me what i got by editing petapon 2 demo's title and ID with notepad..I was on 6.31 frustrated and thought it might work

[m0skit0]

I fixed your errors until it will actually compile

Please, do not give fish, but teach how to fish. Having you doing his programming means he will never learn programming, and thus he will never stop making threads about the same problem again and again...

[daixtr]

The code snippet above is still incomplete. Must still manually declare SetupCallbacks() etc...And also, <pspcallbacks.h> header file does not exist...

[varun]

we have to download that file if u read the tutorial mr expert(s)
