Question

write program in C language.

To get more practice working with files, you will write several functions that involve operations on files. In particular, implement the following functions 1. Write a function that, given a file path/name as a string opens the file and returns its entire contents as a single string. Any endline characters should be preserved char *getFileContents (const char filePath); 2. Write a function that, given a file path/name as a string opens the file and returns the contents of the file as an array of strings. Each element in the array should correspond to a line in the file. Any end line character should be chomped out and not included char **getFileLines (const char *filePath, int *numLines);

uploding the last fucntion it is vary deficult to implement so please wait i am doing it please do no thumbs down there is time factor so please wait. thank you.
