Sample Program Code – High-Performance Computing in C++
// A program to calculate the factorial of a number using recursive and iterative approaches
#include
// Function to calculate the factorial of a number using recursion
int recursiveFactorial(int n) {
if (n == 0) {
return 1;
} else {
return n * recursiveFactorial(n - 1);
}
}
// Function to calculate the factorial of a number using iteration
int iterativeFactorial(int n) {
int result = 1;
for (int i = 2; i <= n; i++) {
result *= i;
}
return result;
}
int main() {
int number;
std::cout << 'Enter a number: '; std::cin >> number;
// Calculate the factorial using recursion
int recursiveResult = recursiveFactorial(number);
std::cout << 'Factorial using recursion: ' << recursiveResult << std::endl;
// Calculate the factorial using iteration
int iterativeResult = iterativeFactorial(number);
std::cout << 'Factorial using iteration: ' << iterativeResult << std::endl;
return 0;
}
Example Output:
Enter a number: 5
Factorial using recursion: 120
Factorial using iteration: 120
Example Detailed Explanation:
The program demonstrates two different approaches to calculate the factorial of a number: recursive and iterative.
1. The program first defines two functions, recursiveFactorial and iterativeFactorial, to calculate the factorial using recursion and iteration, respectively.
2. The recursiveFactorial function takes an integer parameter ‘n’, which represents the number for which the factorial needs to be calculated. It checks if the input ‘n’ is 0, in which case it returns 1 (since the factorial of 0 is defined to be 1). Otherwise, it recursively calls itself with a decremented value of ‘n’ and multiplies the result with ‘n’ to calculate the factorial. This recursive approach continues until ‘n’ becomes 0.
3. The iterativeFactorial function also takes an integer parameter ‘n’ and initializes a variable ‘result’ to 1. It then uses a for loop to iterate from 2 to ‘n’ and multiply each value of ‘i’ with ‘result’. After the loop, it returns the final value of ‘result’, which represents the factorial of ‘n’.
4. In the main function, the program prompts the user to enter a number and reads the input using ‘std::cin’. It then calls the recursiveFactorial and iterativeFactorial functions with the user input as the argument, and stores the results in separate variables.
5. Finally, the program prints the calculated factorials using recursion and iteration using ‘std::cout’ and ‘std::endl’.
This program demonstrates the use of functions, recursion, iteration, input/output operations, and variable manipulation in C++. It follows best practices by separating the factorial calculation logic into separate functions, allowing reusability and modularity. The code is well-documented with comments explaining its logic and purpose.
