How to store a bunch of strings in C?

Question

Here in this problem , have to store n strings (with length no more of 80).

Gets function is not taking the first string (because I think the problem is new line after n). I also tried "fgets(niza,81,stdin)" but was the same.

int main() {
    int n;
    scanf("%d",&n);
    while(n--)
    {
        char niza[81];
        gets(niza);
        transofrmiraj(niza,x);
        printf("%s\n",niza);
    }
    return 0;
}

Don't use `gets`. It's highly deprecated & even the C standard abandoned it and advises against using it. — Jarvis, Jan 03 '21 at 15:45

I have tried and scanf too , but scanf can't save a sentence (stops reading the string when it has a space) and in my case all the strings are sentences — Rinor Ajdini, Jan 03 '21 at 15:50

Your input is probably:

1
String

When you do:

scanf("%d",&n);

it is only removing 1, leaving an empty newline (because you COULD have: 1 first-string-here).

Replacing this with:

scanf("%d\n",&n);

will cause scanf to consume that newline.

This is in regard to your first scanf, reading the number of lines. You can use scanf for the sentences as well ( use. scanf("%[^\n]s",line. - from https://stackoverflow.com/questions/25256697/scanf-doesnt-accept-whitespace ) – Halt State Jan 03 '21 at 15:53
Ohh now i get it. I tried that and fgets and now its working thank you very much – Rinor Ajdini Jan 03 '21 at 16:02
@HaltState `scanf("%[^\n]",line);` -- **not `%[^\n]s`, - no `s` in there.** – Antti Haapala -- Слава Україні Jan 03 '21 at 18:20

You could change:

scanf("%d",&n);

to:

scanf("%d%*c",&n);

So that it will read and discard the newline character after reading the integer number.

Thank you very much all of you who commented. I solve it with scanf("%d\n",&n) and fgets function. – Rinor Ajdini Jan 03 '21 at 16:03
