My program of exercise 1-9

#include <stdio.h>

int main()
{
int flag=1;
int c;

while ((c = getchar()) != EOF)
{
if (c == ' ')
{
flag = 0;
}
else if (flag == 0)
{
printf(" ");
putchar(c);
flag = 1;
}
else
putchar(c);
}
}

It seems run OK,without error or warning in Vc++6.0.
Does it still contain any problems?

Yes. What happens when the input ends with one or more spaces?

yet smaller code..

#include<stdio.h>
main() {

int c;
int flag;

flag = 0;

while ((c = getchar ()) != EOF) {
if (c == ' ') {
if (!flag) {
flag = 1;
putchar (c);
}
}
else {
flag = 0;
putchar (c);
}
}

}
