“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. Ex: The following patterns yield a userScore of 4:

 

simonPattern: RRGBRYYBGY
userPattern:  RRGBBRYBGY

solution

#include <stdio.h>
#include <string.h>

int main(void) {
 char simonPattern[50];
 char userPattern[50];
 int userScore;
 int i;

i = 0;

userScore = 0;
 strcpy(simonPattern, "RRGBRYYBGY");
 strcpy(userPattern, "RRGBBRYBGY");


 while (userPattern[i] == simonPattern[i]) {
 userScore = userScore + 1;
 ++i;
 if (userPattern[i] != simonPattern[i]) {
 break;
 }
 }

printf("userScore: %d\n", userScore);

return 0;
}
