How do I read these warnings

Navigation
2

I'm doing a program that hunts a word from within an array. For this I did 8 functions that scan in all regions, as I need to return in the output the coordinates of the first and last letter.

For example, I need to find the word "house" in the array, the program returns the coordinates of the letter 'c' and the letter 'a' (last letter), as the entries I have and need two values in the output.

I used pointers as parameters, but it's giving a lot of warning. The complete code is still missing.

I've arranged the variables that were being sent with & and are already pointers . I put returns on the functions (I kicked a value just to end with warning ), I made use of the aux variable and assign values to the variables pc and pl . I doubt that I should do what I should, but I solved the problem described in the question, if the question has more details I will improve.
