sqrt

Language/Type: C++ loops

Write a function named sqrt that accepts an integer N as a parameter and returns the square root of N as an integer. The challenge here is that you must not use sqrt or pow or other library functions to calculate the square root; rather, you must compute it yourself. You should return the square root as a truncated integer; for example, the square root of 7 is approximately 2.65, but your function should return 2. You may assume that the value of N passed is a positive integer.

Function: Write a C++ function as described, not a complete program.
