Solution

The problem statement is asking to write a program that takes a string as input, converts it to a double using the atof function and strlen for string length measurement, and then calculates and displays the side length, surface area, and perimeter of a cube.

Here are the steps to solve this problem:

  1. First, we need to include the necessary libraries. In this case, we need stdio.h for input/output functions, stdlib.h for the atof function, and string.h for the strlen function.

  2. Next, we define the main function. Inside this function, we declare a variable to store the input string.

  3. We then get the input string from the user using the scanf function.

  4. We check the length of the input string using the strlen function. If the length is more than 9, we print "Input string is too long" and return from the function.

  5. If the length is less than or equal to 9, we convert the string to a double using the atof function and store it in a variable.

  6. We then calculate the side length, surface area, and perimeter of the cube using the given formulas and store them in separate variables.

  7. Finally, we print the side length, surface area, and perimeter of the cube, each formatted to two decimal places.

Here is a sample code in C language that implements the above steps:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main() {
    char input[10];
    scanf("%s", input);
    
    if(strlen(input) > 9) {
        printf("Input string is too long");
        return 0;
    }
    
    double side_length = atof(input);
    double surface_area = 6 * side_length * side_length;
    double perimeter = 12 * side_length;
    
    printf("%.2f\n", side_length);
    printf("%.2f\n", surface_area);
    printf("%.2f\n", perimeter);
    
    return 0;
}

This program will solve the problem as described in the problem statement.

Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. First method named as 'setDim' takes length and breadth of rectangle as parameters and the second method named as 'getArea' returns the area of the rectangle. Length and breadth of rectangle are entered through keyboard.

You are tasked with implementing a geometry library in C++ that calculates the area and perimeter of various shapes such as squares, rectangles, circles, and triangles. Utilize function overloading to define separate functions for each shape and handle different combinations of parameters appropriately.Your task is to implement the following functions in the Geometry class:1) calculateArea and calculatePerimeter for squares. These functions should take integer as input to represent the side length of the square.2) calculateArea and calculatePerimeter for rectangles. These functions should take the length and width of the rectangle as inputs.3) calculateArea and calculatePerimeter for circles. These functions should take the radius of the circle as input which is not a integer.4) calculateArea for triangles. This function should take the lengths of the three sides of the triangle as inputs. Use Heron's formula to calculate the area.Your implementation should demonstrate the use of function overloading to handle different shapes and parameter combinations.
