Assign numMatches with the number of elements in userValues that equal matchValue.

Question

Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 2, 1, 2} and matchValue is 2 , then numMatches should be 3.

Your code will be tested with the following values:

* matchValue: 2, userValues: {2, 2, 1, 2} (as in the example program above)

* matchValue: 0, userValues: {0, 0, 0, 0}

* matchValue: 50, userValues: {10, 20, 30, 40}

#include <iostream>

#include <vector>

using namespace std;

int main() {

const int NUM_VALS = 4;

int matchValue;

unsigned int i;

int numMatches = -99; // Assign numMatches with 0 before your for loop

vector<int> userValues(NUM_VALS);

cin >> matchValue;

for (i = 0; i < userValues.size(); ++i) {

cin >> userValues.at(i);

}

/* Your solution goes here */

cout << "matchValue: " << matchValue << ", numMatches: " << numMatches << endl;

return 0;

}

4 int main() {

5 const int NUM_VALS = 4;

6 int userValues[NUM_VALS];

7 int i;

8 int matchValue;

9 int numMatches = -99; // Assign numMatches with 0 before your for loop

10

11 cin >> matchValue;

12 for (i = 0; i < NUM_VALS; ++i) {

13 cin >> userValues[i];

14 }

16 /* Your solution goes here */

17 numMatches = 0;

18 for (i = 0; i < NUM_VALS; ++i) {

19 if(userValues[i] == matchValue) {

20 numMatches++;

21 }

22 }

23

24 cout << "matchValue: " << matchValue << ", numMatches: " << numMatches << endl;

25

26 return 0;
