- Search Benchmarks

Create a New Project called YourLastnameSearch.

int array[20] = {78, 45, 33, 1, 6, 41, 99, 54, 73, 28, 101, 60, 21, 82, 11, 15, 654, 36, 52, 70};

Write a program that has an array of 20 integers. (You must use the above array.)

It should call a function that uses the linear search algorithm to locate one of the values.

The function should keep a count of the number of comparisons it makes until it finds the value.

The program then should call a function that uses the binary search algorithm to locate the same value.

It should also keep count of the number of the comparisons it makes. Display these values on the screen.

Here is the code that I wrote and it did not work. Please help me find out my error.
