[C] getchar() returns too quickly

[yoonkwun]

Hi, I am trying to get user input through getchar(). However, it seems that the second time I call it, it returns immediately.

#include <stdio.h>

int main()
{
    getchar();
    getchar();
    return 0;
}

This would only take input one time. Is there any way to avoid this undesired behavior? Thanks

This would only take input one time.

Nope, it takes input two times :P The first is the character you type and the second is the newline character generated by the pressing of enter. Check it out like this: if you don't enter a character it takes two enter key-presses to quit the program.

Check if the result for the first getchar() was a '\n'. Only call getchar() a second time if it wasn't.

you can use #include <iostream.h> and use (cin>>var;) to read from the keyboard the inf.
before the return use cin.get(); whit this yoou have press one key to exit of your program.

Keep the console open long enough to see your program's output

All user input ends in ENTER
