Why doesn't getchar() wait for me to press enter after scanf()?

Question

I am learning C and I\'m using \"getchar()\" to stop the command windows so I can see the exercises am doing but it just doesn\'t work. heres a sample:

#incl         


        

Answer 1

As mentioned already scanf leaves \n behind after reading user input.

Soultion: add getchar() straight after scanf.

That compensates scanf deficiency.

i.e.

int value; 
printf("1. option 1.\n2. option 2.\n3. option 3.\n4. Exit\n\nMake an option: "); 
scanf("%d", &value);
getchar();
switch (value)
