Compute Specified Expression

Write a program in C++ to compute the specified expressions and print the output.

Sample Solution:

C++ Code:

#include <iostream> // Including the input-output stream header file

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
    cout << "\n\n Compute the specified expressions and print the output:\n"; // Outputting a message indicating the purpose of the program
    cout << "------------------------------------------------------------\n"; // Outputting a separator line

    // Calculating and outputting the result of the given expression
    cout << " Result of the expression "
<< "(25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) is : " // Outputting the expression
<< (25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) << "\n"; // Calculating and outputting the result of the expression

    return 0; // Returning 0 to indicate successful program execution
}

Sample Output:

 Compute the specified expressions and print the output:              
------------------------------------------------------------          
 Result of the expression (25.5 * 3.5 - 3.5 * 3.5) / (40.5 - 4.5) is : 2.13889
