Question

#include

{
    char F,C;

    printf(\"Do you have a Fever? y/n\\n\");
    F = getchar();

    printf(\"Do you have a runny nose or c         


        

Answer 1

When you enter a character ,it is stored in F,then when you press enter,it is stored in stdin buffer and when next getchar() comes it reads it's input from the stdin buffer ,for this use fflush(stdin) before every getchar() you use.
