Write A Flowchart And C Code For A Program That Does The Fol
This assignment involves developing a flowchart and C programming code for a simple numerical analysis task. The primary objective is to create a program that solicits a number from the user, evaluates the input, and then either reports an error or performs calculations based on the input value. This exercise encompasses designing an algorithm represented visually via a flowchart and then translating that logic into executable C code.
Problem Description
The program must begin by prompting the user to enter a numerical value. Once the user inputs a number, the program uses an if statement to determine whether the number exceeds 1. If the number is less than or equal to 1, the program outputs an error message indicating invalid input or a similar notification. Conversely, if the number is greater than 1, the program calculates the square and cube of the number and displays the results clearly to the user.
Flowchart Development
The flowchart begins with the start symbol. It proceeds to a process block where the program prompts the user for a number. The next step involves a decision point: Is the entered number greater than 1? If the answer is no (the number is less than or equal to 1), the program moves to an output block displaying an error message, followed by an end symbol. If the answer is yes, the program moves to process blocks
where it calculates the square and cube of the number, then outputs these results before ending.
C Programming Implementation
The following C code provides a direct implementation of this logic:
#include <stdio.h> int main() {
double number, square, cube;
// Prompt the user for input
printf("Please enter a number: ");
scanf("%lf", &number);
// Check if the number is greater than 1 if (number > 1) {
// Calculate the square and cube square = number * number;
cube = number * number * number;
// Display the results
printf("Number: %.2f\n", number);
printf("Square: %.2f\n", square);
printf("Cube: %.2f\n", cube);
} else {
// Output error message
printf("Error: The number must be greater than 1.\n"); } return 0;
Summary
This program effectively demonstrates decision-making in programming by validating user input and performing conditional calculations. Creating a flowchart to visualize this logic helps in understanding the program flow prior to coding. The C implementation provided follows best practices for input validation and output formatting, making it suitable for educational purposes or simple numerical operations.
