scanf() function doesn't work? [duplicate]

Answer 1

Instead of fflush(stdin); scanf("%c", &c);

1.use scanf with extra space

scanf(" %c",&c); 

or

2.use getchar() two times , first time reads '\n' which is entered after giving integer input and second time call ask you for give input as c:

getchar();
c=getchar();

would help you.
