Answer to Question #145451 in C++ for lalith

Question

Write a program that declares three one-dimensional arrays named miles, gallons, and mpg(miles per gallons). Each array should be capable of holding 10 elements. In the miles array, store the numbers 240.5, 300.0, 189.6, 310.6, 280.7, 216.9, 199.4, 160.3, 177.4, and 192.3. In the gallons array, store the numbers 10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, and 8.4. Each element of the mpg array should be calculated as the corresponding element of the miles array divided by the equivalent element of
the gallons array: for example, mpg[0] =miles[0] / gallons[0]. Use pointers when calculating and displaying the elements of the mpg array.

Answer 1

#include <iostream>


int main()
{
	const int N = 10;
	const float miles[N] = { 240.5, 300.0, 189.6, 310.6, 280.7, 216.9, 199.4, 160.3, 177.4, 192.3 };
	const float gallons[N] = { 10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, 8.4 };
	float mpg[N];


	for (int i = 0; i < N; ++i)
	{
		*(mpg + i) = (*(miles + i)) / (*(gallons + i));
	}


	for (int i = 0; i < N; ++i)
	{
		std::cout << "Miles: " << *(miles + i) << " ";
		std::cout << "Gallons: " << *(gallons + i) << " ";
		std::cout << "Mpg: " << *(mpg + i) << "\n";
	}


	return 0;
}
