'printf' followed by 'scanf' requires pressing ENTER key twice to accept input

Question

I\'m a complete beginner in C programming and I have a question. I\'ll bring a simple code as an example:

#include 

int main( void )
{
    int x         


        

Answer 1

It's the "\n" in your call to scanf. Remove that and scanf will return after scanning the integer value you requested.

Note: This has nothing to do with the fact that the scanf call is preceded by a printf.
