Randomly choosing a word from a text file in C

I'm quite new at programming and I'm trying to code Hangman. I have 10 words saved in a textfile in the same folder as the code and I want the program to randomly choose a word and save that word into a character array.

I've googled and looked around but I can't seem to figure out how to do it. Do I use something like fopen() and rand()?


assuming the words are written one per line , here's a small piece of code that'll do that :

FILE* fp = NULL;
char words[20];
int i = 0 , ran = 0;
fp = fopen("path" , "r+");
for(; fgets(words , sizeof(words) , fp) ; i++)
ran = rand() % i;
for(i = 0 ; i < ran ; i++)
    fgets(words , sizeof(words) , fp);

 printf("%s\n" , words);

beware of not having a new line character at the end of you file because it will be considered as a word and will sometimes be returned to you

It depends on how these words are saved in a file. My first thought is to choose random number and then read a word which is written in a line that has chosen number. But your words have to be written one per line.

You can do this in three steps:

  1. Read all words from file to char words[N][100] (here N=10). In C, you can do this as follows:

    char words[10][100];
    int i = 0;
    while(10>i && fgets( words[i++], 100, file) );
  2. Generate a random number i within [0,N-1].

    int i = rand() % 10;
  3. Return words[i][].
