Substrings in C+ : I am having trouble with this problem any tips on how to solve it would be appreciated. Thanks in advance. "This function finds the first occurrence of toFind in original and returns an integer representing the index of the first element of the toFind substring in original.  For example if toFind was 'man' and original was 'superman' the function would return 6 since the begining of 'man' in 'spiderman' is position 7.  If the function does not find a substring it should return -1."
