Convert the square inch to square yard

The conversion of units is a common task in programming, especially when dealing with measurements. In this article, we will focus on converting square inches to square yards using a simple program. We'll walk through the problem statement, explain the solution with suitable examples, provide the algorithm, and analyze the time complexity of the code.

Problem Statement

The problem is to convert a given area in square inches to the corresponding area in square yards. This involves taking a value in square inches, dividing it by the conversion factor, and obtaining the equivalent area in square yards. The formula for conversion is:

Square Yards = Square Inches / 1296

Example

Let's say we have an area of 2592 square inches. To convert this to square yards, we would use the formula:

Square Yards = 2592 / 1296 = 2

So, 2592 square inches is equal to 2 square yards.

Idea to Solve the Problem

To solve this problem, we need to write a C program that takes a value in square inches as input, performs the conversion using the formula, and then outputs the corresponding value in square yards.

Pseudocode

Here's the pseudocode for the solution:

function square_inch_to_square_yard(square_inch)
    square_yard = square_inch / 1296
    output "Square inch:", square_inch, "Square yard:", square_yard
end function

main
    square_inch_to_square_yard(1)
    square_inch_to_square_yard(2021)
    square_inch_to_square_yard(1500.6)
end main

Algorithm Explanation

  1. The square_inch_to_square_yard function takes a single parameter, square_inch, which represents the area in square inches to be converted.
  2. Inside the function, the square inch value is divided by 1296 to calculate the equivalent area in square yards.
  3. The calculated values of square inch and square yard are then printed as output, along with appropriate labels.
  4. In the main function, the square_inch_to_square_yard function is called three times with different test values to demonstrate the conversion.

Program Solution

//C Program 
//Convert the square inch to square yard
#include <stdio.h>
 //Find the square inch of given square yard
void square_inch_to_square_yard(double square_inch)
{
	// Calculate square yard 
	// Formula : (Square inch / 1296)
	double square_yard = (square_inch / 1296);
	printf("Square inch : %lf, Square yard : %lf\n", square_inch, square_yard);
}
int main()
{
	//Simple test
	square_inch_to_square_yard(1);
	square_inch_to_square_yard(2021);
	square_inch_to_square_yard(1500.6);
	return 0;
}

Output

Square inch : 1.000000, Square yard : 0.000772
Square inch : 2021.000000, Square yard : 1.559414
Square inch : 1500.600000, Square yard : 1.157870

Time Complexity

The time complexity of the conversion process is constant for each conversion since it only involves simple arithmetic operations (division). Therefore, the time complexity of the code is O(1), which signifies that the execution time remains constant regardless of the input size.
