scanf/cin problem

[SASIKUMAR JP]

Hi,
I have written simple code,which will accepts integer input.if i
give character as input,it will not wait for user input next time.what
is the problem in scanf or my code.

Sample Code:

#include <stdio.h>

int main(){
int ch;
while(1){
/* It accepts integer input,if i give character as input,it
will not wait for user input next time */
scanf("%d",&ch)
if(ch == 0){
break;
}
printf("%d",ch);
}
return 0;
}

I have tested this code with Solaris 5.8 with gcc compiler.

Please some one help me to find out problem in code/scanf.

Thanks
Sasikumar
