int countMatches(int custPIN[], int databasePIN[], int size) {

int matches = 0;

for (int index = 0; index < size; index++) { if (custPIN[index] == databasePIN[index]) matches++; } return matches; }

int matches = 0;

for (int index = 0; index < size; index++) { if (custPIN[index] == databasePIN[index]) matches++; } return matches; }

Consider the testPIN function used in Program 7-21. For convenience, we have reproduced the code for you below. Modify this function as follows:change its type to int change its name to countMATCHES make it return the number of corresponding parallel elements that are equal.

bool testPIN(int custPIN[], int databasePIN[], int size)

{

if (countMatches(custPIN, databasePIN, size)== size)

return true;

else

return false;

}

if (countMatches(custPIN, databasePIN, size)== size)

return true;

else

return false;

}

Again, consider the testPIN function used in Program 7-21. For convenience, we have reproduced the code for you below.Rewrite the function body of this function so that instead of using iterating through the elements of the parallel arrays, it returns true or false by calling countMatches the function defined in the previous exercise (10988), and checking its return value.
