The standard library function strlen() (found in string.h) returns the number ofcharacters in a string, not including the terminating NUL ('\0') character. Write your own StringLength() function that does exactly the same thing. Write a shortmain() program to declare and initialize a string. Pass the string toStringLength() to demonstrate that it can return an integer value representing the number of characters in the test string. Use a cout statement in main() to printout the length of the string.

Please note: Your function should count the characters in the string, not accesssome C++ library function or method. DO NOT #include or . There should be no console input or output in the function. All input/output should be in main().
