Problem:
While reviewing the code, I noticed that the value of Pi (ฯ) is hardcoded as 3.14 in the function, instead of utilizing the built-in library value.
cout << "\nArea of Circle = " << 0.5 * 3.14 * r * r;
Suggestion:
It's recommended to use the built-in library value for Pi (M_PI constant from or <math.h> header file) rather than hard coding it. This not only ensures accuracy but also improves maintainability and readability of the code.
