C++ Coding: Arrays Implement a two-dimensional character array. Use a nested loop to store a 12x6 flag. 5 x 2 stars as * Alternate = and – to represent stripe colors Use a nested loop to output the character array to the console.

Given string userString on one line, character newChar on a second line, and integer strIndex on a third line, change the character at index strIndex of userString to newChar. Ex: If the input is: garlic Z 0 then the output is: Zarlic Note: Assume the length of string userString is greater than strIndex. #include <iostream> #include <string> using namespace std;   int main() {    string userString; char newChar; int strIndex;      getline(cin, userString); cin >> newChar; cin >> strIndex;        /* Your code goes here */      cout << userString << endl;      return 0; }
