Проблемы с проверкой орфографии

Question

Я пытаюсь закончить свой проект проверки орфографии и имею несколько проблем. Я пытаюсь использовать strlen и strcmp, чтобы сравнить слова в статье и словаре друг с другом, но компилятор говорит мне, что идентификаторы «strlen» и «strcmp» не определены. Я не уверен, что делать здесь. Кроме того, когда я загружаю char(article) в int ArticleLength, он говорит мне, что я не могу использовать int с char. Я очень новичок и нуждаюсь в некоторой помощи. Вот мой код.

#include <stdio.h> // provides declarations for printf and putchar 
#include <stdint.h> // provides declarations for int32_t uint32_t and the other (new) standard C type 
/* You must write this function (spellCheck). Do not change the way the function is declared (i.e., it has 
* exactly two parameters, each parameter is a standard (mundane) C string (see SpellCheck.pdf). 
* You are expected to use reasonable programming style. I *insist* that you indent 
* reasonably and consistently in your code. I strongly encourage you to avoid big functions 
* (while there are always exceptions, a good rule of thumb is about 15 lines in a function). 
* So, plan on implementing spellCheck by writing two or three other "support functions" that 
* help make the actual spell checking easier for you. 
* There are no explicit restictions on using functions from the C standard library. However, 
* for this project you should avoid using functionality from the C++ standard libary. You will 
* almost certainly find it easiest to just write everything you need from scratch!

Answer 1

Вам необходимо включить заголовок, который определяет strlen и strcmp

#include <string.h> 

Позже: редактирует на ваш вопрос удалили другие включают в себя. Вам также необходимо #include <stdio.h>
