Hello my teacher told me to create a program that returns the substring of a string given the starting index of the substring and its length. For example, the user has entered the string "The quick brown fox" and has entered 7 as the starting index of the substring and 5 as the length. Then, the program should return the substring "brown". Write a function named substring that returns a pointer and accepts a pointer and 2 integers. The first integer refers to the starting index of the substring in the text and the second the length of the substring. Problem is that I am still a begginer in c and he did not teach us anyhing about substrings. Could you please help me out by telling me where to begin and how to progress. Thank you
