Need help with the following. Thanks:) Second image is the main.cpp that needs to be edited

# Problem Complete the LinearSearch function so that it returns the index at which the number was found in the array or -1 otherwise. # Sample Inputs and Outputs NUMBERS: 2 4 7 10 11 32 45 87 Enter a value: 11 Found 11 at index 4. NUMBERS: 2 4 7 10 11 32 45 87 Enter a value: 100 100 was not found. #include using namespace std; int LinearSearch(int numbers[], int numbersSize, int key) { /* Your solution here */ return -1; /* not found */ } int main() { int numbers [] { 2, 4, 7, 10, 11, 32, 45, 87 }; const int NUMBERS_SIZE = 8; int i; int key; int keyIndex; cout > key; keyIndex = LinearSearch(numbers, NUMBERS_SIZE, key); if (keyIndex -1) { cout
