Hi, I did this small program to test my input. It's working, but I want to
get a clue in order to avoid the fact that somebody can enter 2 characters
for the second question and of course because I set only one character for
the second question, the second character will be in the first of my third
question. I was clear?
I think I have the same problem when I answer to the first question more
than 1 int, "enter one integer" doesn't stop be written on the screen. How
can I solve the problem. I thought I had to use fflush(stdin) in order to
erase everything from the input stream, but doesn't work.
Thanks for helping me.
here the prog:
#include <stdio.h>
int main(void)
{
char c[2],move;
int check=0,x,y,z,stepcode,test;
clrscr();
printf("\n\n");
do {
printf("\rEnter 1 integer:");
fflush(stdout);
test=scanf("%d",&stepcode);
scanf("*[^\n]");
if ((stepcode<10)&&(stepcode>0)) check=1;
} while ((test!=1)||(check==0));
printf("\nEnter one character:");
fflush(stdout);
scanf("%1s",c);
scanf("*[^\n]");
move=c[0];
do {
printf("\nEnter three integers:");
fflush(stdout);
test=scanf("%d%d%d",&x,&y,&z);
scanf("*[^\n]");
} while (test!=3);
printf("\n\nstepcode=%d move=%c x=%d y=%d z=%d",stepcode,move,x,y,z);
printf("\n\nPress a key to close the program ...");
getch();
exit (0);
}
