Strtok with space
WebJust like strtok, this function splits the string into several tokens which can be accessed by successive calls to strtok_r. The difference is that, as in wcstok , the information about the next token is stored in the space pointed to by the third argument, save_ptr , which is a pointer to a string pointer. WebYou may use either C or C++ for this assignment. This program will read an input file which will have a series of words using the English Alphabet characters a-z, A-Z.
