I just finnished my hangman game and as a last step I am doing some code cleanup and optimization, but I can't seem to understand why I receive the following two warnings:
warning: incompatible implicit declaration of built-in function 'strlen'
warning: incompatible implicit declaration of built-in function 'strcpy'
The code in which they are used is here:
for(i = 1; i <= random; i++)
fgets(word, 100, f);
fclose(f);
for(i = 0; i < strlen(word); i++)
if(word[i] == '\n')
word[strlen(word)-1] = '\0';
lungime = strlen(word);
strcpy(word2, word);
What I done was to read a random word from a file, using fgets. After this, I removed the '\n' which fgets automatically puts. Finally, I made a copy of the word in word2.
Used libraries:
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
Declaration of variables:
int random, n = 0, i, j, lengh, tries = 5, ok = 0, error = 0;;
char word[100], word2[100], tried_letters[50], auxch;
Note: everything works perfect in my program, but I receive those two warnings which I would like to get rid of.
Thanks in advance.
