Lab No 11deign A C Application That Will Recive Two In Intger Valu

Design a C++ application that receives two integers from the user (a and b). The application determines whether a is evenly divisible by b and displays an appropriate message. The program prompts the user for two integers, then verifies and reports whether the first number is divisible by the second.

Divisibility is a fundamental concept in arithmetic and number theory, referring to whether one integer can be divided by another without leaving a remainder. The purpose of this program is to create an interactive application in C++ that accepts two integers from the user and determines if the first integer (a) is evenly divisible by the second (b). In practical terms, this involves performing a modulus operation and analyzing the result to provide a clear, user-friendly outcome.

The process begins with the program prompting the user to input two integers. These inputs are stored in variables, for instance, a and b. It is critical that the application handles user input errors gracefully, though for this basic example, input validation is minimal. Once the values are obtained, the program conducts a divisibility check by computing a % b. If this operation yields zero, it confirms that a is divisible by b; otherwise, it indicates the contrary.

To structure the program efficiently, functions are employed for input collection and verification, which enhances readability and modularity. The input function prompts the user and reads the two integers, while the verification function performs the divisibility check and outputs the result. This modular design adheres to best practices in programming, facilitating debugging and future modifications.

The implementation of the program uses standard C++ libraries, particularly <iostream>, to manage input and output operations. The code begins with the necessary headers and uses the std namespace for simplicity. The main function orchestrates the process by calling input and verification functions sequentially, ensuring the logical flow is straightforward and easy to follow.

Here's the complete implementation of the described application:

include <iostream>


using namespace std;


// Function prototypes


void my_input(int, int);


void my_verify(int, int);


int main() {


int a = 0, b = 0;


my_input(&a, &b);


my_verify(&a, &b);


return 0;


}


void my_input(int f1, int f2) {


cout << "Please provide me with an integer value (a): " << endl;


cin >> *f1;


cout << "Please provide me with an integer value (b): " << endl;


cin >> *f2;


cout << "This application will determine if the first number is evenly divisible by the second." << endl;


}


void my_verify(int f3, int f4) {


if (*f4 == 0) {


cout << "Division by zero is undefined. Cannot determine divisibility." << endl;


return;


}


if (f3 % f4 == 0) {


cout << "The number " << f3 << " is evenly divisible by " << f4 << "." << endl;


} else {


cout << "The number " <> f3 << " is not evenly divisible by " << f4 << "." << endl;


}


}

This program effectively guides the user through input collection, performs the divisibility check, and provides clear output. It also includes a safeguard against division by zero, which is essential for any real-world application involving user inputs.

In conclusion, the application demonstrates fundamental programming constructs such as function usage, user interaction, control flow, and condition checking in C++. By modularizing input and verification tasks, the program adheres to clean coding standards. Such an approach facilitates understanding and scalability, which are important considerations in software development focused on mathematical computations like divisibility checks.
