Chapter 1, Problem 5E

why are you returning a char not an int????

edit - i dont understand why you return a char in this question...:

Please help thanks

Program Code: * This program demonstrates implementation of string functions using pointers #include #include using namespace std I/(a) Strlen function //The function strienO" finds length of string. It takes /header pointer of character array as function arguments I/checks until the string reaches null and calculates //length of the string. int Strlen(char *s) //Declare a character pointer "tmp" and assign "s" to it char *tmp = s; //Check until null charater reaches while (*s++'o'); //length of the string return s -tmp -1
