C++ code working but c code gives WA

My c++ code for the problem GUESSG from june challenge is partially accepted,but similar
implementation in c is giving WA.Can I know the reason why the c code is not working.

The c code - https://www.codechef.com/viewsolution/35885267

Both endl and \n serve the same purpose in C++ and c – they insert a new line. However, the key difference between them is that endl causes a flushing of the output buffer every time it is called, whereas \n does not.

So whenever you are using C language and ‘\n’ to solve interactive problem don’t forget to use fflush everytime you output something.

Thanks a lot !


As you said I have used fflush(stdout),but still the code is not working.
here’s my code - https://www.codechef.com/viewsolution/35885289

also use scanf("%*c%c",&c).
So what *c will do is it will ignore the newline and scan for the character.

as you are reading a character after reading an integer so without using scanf("%*c%c",&c) the first while loop iteration will take up the newline character as input and continue and blah blah…too much theory.

Simply use scanf("%*c%c",&c) instead of scanf("%c",&c).
Hope this would help.
