Question
Chapter 10.4, Problem 10.7CP
Program Plan Intro
“strlen” function:
The “strlen” function accepts a string as an argument and returns the full length of the string, but it will not include the null character (‘\0’).
Example:
Consider the example of the “strlen” function is as follows:
char a [10] = "Hai";
int value = strlen (a);
Here, the variable “value” will store 3, because the length of the “a” string is 3.

(Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed.
