Question

Assume that the function strlen() does not exist.



Your task is to code a function named myStrLen().



As a parameter, it takes a cstring and the maximum size of the cstring. It

returns the length of the cstring. The length is the number of ASCII

characters up to but not including the null terminator ('').



Syntax: int myStrLen(const char[], const int SIZE);



The program main() is coded below. Do not modify main().



Add your code after the TODO and between the // STUDENT CODE BEGINS and //

STUDENT CODE ENDS.

const int SIZE = 81; // max size + 1 of cstring

char line[SIZE];

} while (choice == "Y" || choice == "y");



cout << "End of program...." << endl;

return 0;
