Searching an Array of Strings from User Input in C - c

Question

I've got this homework assignment where we get the user to enter the amount of lines of strings they desire, they then proceed to enter them which gets stored in a 2D Array (thus creating an array of strings). Then a switch case menu will be displayed which should
Search a character entered by the user, returns the amount of times the character occurred in the array
Search a word entered by the user, returns the amount of times the word occurred in the array
Have the user enter a specified word length and return the amount of times words of the specified length occur.
I have a couple problems with my code. The program runs without errors from the compiler. The searchByCharacter function works fine but the searchByWord only returns a value of 0 regardless of any word inputted and nothing happens after I input a number for the searchByLength function. The program freezes after I enter a length once I select the searchByLength function. I've been at this for a while and I don't know where I'm going wrong.
