3. Introduction to C++ Programming for Arithmetic Operations C++ programming is a powerful language used for performing arithmetic operations. This presentation provides an overview of C++ programming and its applications in arithmetic operations. It covers the basics of C++ programming, its advantages, and how to get started with it.

4. Getting Started with C++ What is C++? C++ is a powerful, general-purpose programming language. Developed by Bjarne Stroustrup at Bell Labs in the 1980s. An extension of the C programming language with additional features. Why C++? C++ allows direct manipulation of memory, offering fine control over system resources. While it offers low-level control, C++ also provides high-level abstractions, making complex tasks more manageable. Many existing systems and libraries are written in C++, making it essential for maintenance and integration.

5. Addition of Entered No in C++ The Addition Algorithm 1 Step 1: Input two numbers Begin by declaring variables to store the numbers and the result. For example, int num1, num2, sum; 2 Step 2: Perform the addition Add num1 and num2 and store the result in a variable, such as sum = num1 + num2; 3 Step 3: Display the result Output the result to the user using std:: cout . For example, std:: cout << "Sum: " << sum << std:: endl ;.

6. Subtraction of Entered No in C++ The Subtraction Algorithm Declare variables to store the numbers and the result. For example, int num1, num2, difference; 1 Step 1: Input two numbers Subtract num2 from num1 and store the result in a variable, such as difference = num1 - num2; 2 Step 2: Perform the subtraction Output the result to the user using std:: cout . For example, std:: cout << "Difference: " << difference << std:: endl ; 3 Step 3: Display the result If the result is negative, indicate it appropriately. 4 Step 4: Handle negative results

7. Multiplication of Entered No in C++ The Multiplication Algorithm Step 1: Input two numbers Declare variables to store the numbers and the result. For example, int num1, num2, result; Step 2: Perform the multiplication Multiply the two numbers using the '*' operator in C++. Multiply num1 and num2 and store the result in a variable, such as result = num1 * num2; Step 3: Display Result Output the result to the user using std:: cout . For example, std:: cout << "Multiplication Result: " << result << std:: endl ;

8. Division of Entered No in C++ Declare Variables: Declare variables to store the numbers and the result. For example, float num1, num2, quotient;. User Input: Prompt the user to input the dividend (numerator) and store it in num1. Similarly, prompt the user to input the divisor (denominator) and store it in num2. Perform Division: Check if num2 is not zero (to avoid division by zero). If not zero, divide num1 by num2 and store the result in a variable, such as quotient = num1 / num2;. Display Result: Output the result to the user using std:: cout . For example, std:: cout << "Quotient: " << quotient << std:: endl ;. If num2 is zero, output an error message indicating division by zero.

9. Coding the Program in C++ Step-by-Step Coding Process Step 1: Include necessary libraries Include the necessary C++ libraries for input/output operations. Step 2: Declare variables Declare variables to store the input and output values. Step 3: Implement the algorithm Write the code to perform the desired arithmetic operation.

10. Running the Program and Viewing Results Executing the Program 1 Step 1: Compile the program Use the C++ compiler to compile the program code . 2 Step 2: Run the program Execute the compiled program to perform the arithmetic operation. Actual Program ahead

11. Understanding the Output Interpreting the Results Examine the output of the program to understand the computed result. 1 Step 1: Analyze the output Check for any errors or exceptions that may have occurred during program execution. 2 S tep 2: Handle errors Compare the program output with expected results to ensure correctness. 3 Step 3: Verify correctness If the results are incorrect, debug the program and rerun it for verification. 4 Step 4: Re-run if necessary

12. Conclusion and Recap In conclusion, this presentation provided an overview of C++ programming for arithmetic operations. It covered the basic concepts of C++, getting started with the language, and detailed explanations of addition, subtraction, multiplication, and division operations. It also discussed the coding process, running the program, understanding the output, and provided a brief recap of the topics covered .
