Question

Write an application that allows user to input the height and width of a rectangle. It should output the area and perimeter of the rectangle. Use methods for entering the values, performing the computations, and displaying the results. Results should be formatted with one position to the right of the decimal and printed number aligned in a tabular display.
I need help with

Answer 1

// program to display area and perimeter of rectange

#include <stdio.h>

void getInput(float* height, float* width)
{
   printf ("Enter the height: ");
   scanf ("%f", height);
   printf ("Enter the width: ");
   scanf ("%f", width);
}

float getArea(float h, float w)
{
   float area = h * w;
   return area;
}

float getPerimeter(float h, float w)
{
   float perimter = (2* h) + (2 * w);
   return perimter;
}

void displayResult(float h, float w, float area, float perimter)
{
   printf("Height\tWidth\tArea\tPerimeter\n");
   printf ("%.1f\t%.1f\t%.1f\t%.1f\t\n", h, w, area, perimter);

}

int main()
{
   float height, width, area, perimter;

   getInput(&height, &width);

   area = getArea(height, width);
   perimter = getPerimeter(height, width);
   displayResult(height, width, area, perimter);

   return 0;
}

Enter the height 4.33 Enter the width: 7.81 Height Width Area 4.3 Perimeter 24.3 7.8 33.8

As per the question, one decimal placed is showed in the output.

The code is in C programming language.
