Write a complete C program that takes an expression with parentheses as input and returns whether the parentheses in the expression are balanced or not. Use any expression with at least five pairs of parentheses and one extra. See the example below for a sample. Also, cover the balanced case. Hint: Use a stack for the solution.

Example:

Input: $`\{()\})`$

Output: The parentheses in the expression are not balanced.

Explanation: The extra closing parenthesis $`)`$ has no corresponding opening parenthesis, leading to an unbalanced expression.

Ensure your code runs smoothly and generates the desired output discussed in the class.

Your code must be well$-$indented and documents with appropriate comments.
