strange problem

can someone tell me why the following program does not display the text that
have been collected?

#include <stdio.h>

int main()
{
char c, sentence[80];
int i = 0;

puts("Enter a line of text:\n");
while ((c = getchar()) != '\n' );
{
sentence[i] = c;
i++;
}

sentence[i] = '\0'; /* Insert null at end of string */

puts("\nThe line entered was :");
puts(sentence);

return 0;
}

But there are other potential problems. Why aren't you using
std::string instead of raw arrays
(http://www.parashift.com/c++-faq-lit...tml#faq-34.1)?

Because you've an extra ';' at the end of the 'while' line.

program I wrote in C (this was 1984) as a professional developer.

for (i = 0 ; i < N; i++);
{
/* initialize some_array[i] */
}

We've all been there, done that.

problem' is pretty non-descript, don't you think?

2. Buy yourself a decent compiler. Mine will issue a warning in above cases.

3. Why don't you try to debug your code? Tracing once through it would
have solved this in no time.

When I was learning C, I had a sheet of paper with the heading, "Having
Problems Dummy?", where I recorded various gotchas that bit me. Old
Turbo C wasn't as forthcoming with warnings as some of the modern
compilers, so stuff like the above or:

if (y = 1)
{
}


Or not passing pointers to scanf(), used to pass right on through.

4. Post this to comp.lang.c, as this is pure C, not C++.

You are right about the subject. I am sorry.

I am using the Dev-C++ because I heard that it is the best freeware
environement, but the error explanations are awfull. Can you suggest an
other environement for C++ developement?

The 'error explanations' are NOT awful! YOU must learn!!!
