code problem

pls can anyone help me ?? i have a problem with the following code...The code is ..

Code:

main()
{
   int a,b;
   scanf("%d%d",&a,&b);
   char x;
   scanf("%c",&c);
   switch(x);
   {
     case'A':
     printf("good");
     break:
     default:
     printf("bad");
}

The output of following code in C is "bad" but problem is that during execution,it only asks for the values of a &b.It doesnt ask for the value of x whose datatype is char.Why So?
The Same program if executed in C++ using cout and cin works fine n even asks for the value of x.Why So that the above code works for C++ and not in C?

pls help me...

Code:

scanf("%c",&x);

use \n before

use \n before %c in scanf statement as shown below......
main()
{
int a,b;
scanf("%d%d",&a,&b);
char x;
scanf("\n%c",&c);
switch(x);
{
case'A':
printf("good");
break:
default:
printf("bad");
}
