Re: HELP!! Two questions from <<the c programming language>>

Algorithm trim_space

while EOF
do
begin
input char
if char = space then
begin
if flag = 0 then
begin
let flag = 1;
print char;
end
end
else
begin
let flag = 0
print char
end
end
goto step 2
end while


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?
