Question

"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. C++
Ex: The following patterns yield a userScore of 4:

Ex: The following patterns yield a userScore of 9:

simonPattern: R, R, G, B, R, Y, Y, B, G, Y

userPattern: R, R, G, B, B, R, Y, B, G, Y

Result: Can't get test 2 to occur when userScore is 9

Answer 1

Answer:

#include <iostream>  // includes input output functions

#include <string> // used for string functions

using namespace std;   // identifies objects like cout , cin

int main() {  // body of the main function

int index;   // index position of the elements

simonPattern = "RRGBRYYBGY";   //stores simon pattern

userPattern = "RRGBBRYBGY";   //stores user pattern

int userScore = 0;  // used to store the user score

// loop compares characters of user and simon patterns

for ( index = 0; userPattern[index] == simonPattern[index]; ++index) {

     userScore = userScore +1; // adds to the user score

     if (userPattern[index] != simonPattern[index]){

//if user and simon pattern do not match

        break;      }   } // breaks the loop

cout << "userScore is  " << userScore; // prints the user score

Explanation:

The program compares the user pattern to simon pattern character by character and keeps adding one to the user score if the characters of both simon and user patterns match. The loop breaks if the character of user pattern does not match with that of simon matter. At the end the calculated user score is displayed in the output.
