help with if statement and ENTER

printf("enter choice: ");
scanf("%d", &choice);

if(choice==1)
do this;
if(choice==2)
do that;
if(choice==(Enter key))
do something;

How can i make so that when the user hits the enter key, it records that as a choice and does whatever is in that if statement, instead of just going to the next line and waiting for a proper input.

When ENTER key is pressed, it returns a newline character ('\n').just check for the new line character and proceed.And make sure the variable yor collecting the input should be of type CHAR or UNSIGNED CHAR

you mean like this?

char choice;

printf("enter choice: ");
scanf("%c", &choice);

if(choice==1)
do this;
if(choice==2)
do that;
if(choice=='\n')
do something;

i tried that but it doesn't work. Or do you mean something else?

Hi xhoangx,

i think the mistake u made is checking the values in if statement.if u want to compare some value that should be in single quotes(' ') or else it will take the equavalent character. This is working well.i'm using VC++ 6.0.

Code:

---

char choice;

printf("enter choice: ");
scanf("%c", &choice);

if(choice=='1')
do this;
if(choice=='2')
do that;
if(choice=='\n')
do something;
