Solution Source Code

Code Overview

1. Header Files and Namespace:

• <iostream> is included for input and output operations.
• <string> is included for potential future use (not used in this program).
• <cmath> is included to use sqrt() and pow() for mathematical calculations.
• using namespace std; allows the use of standard functions without prefixing them with std::.

2. User Input Function (ReadTriangleData)

• Uses reference parameters (float &A, float &B, float &C) to modify the values directly.
• Prompts the user to enter the three sides of a triangle.

3. Area Calculation Function (CircleAreaByATriangle)

• Takes the three sides (A, B, C) as input.
• Computes the semi-perimeter (P) using:

• Computes the radius (T) of the inscribed circle using the formula:

• Computes the circle area using:

float Area = PI * pow(T, 2);

• • pow(T, 2) calculates T².
  • PI is defined as 3.141592653589793238 for precise calculations.
• Returns the computed area.

4. Output Function (PrintResult)

• Receives the computed area as a parameter.
• Prints "Circle Area = [Area]".

5. Program Execution (main())

• Calls ReadTriangleData() to get user input.
• Calls CircleAreaByATriangle() to compute the inscribed circle's area.
• Calls PrintResult() to display the result.
• Returns 0 to indicate successful execution.
