Answer to Question #288547 in C++ for fisiwe

Question

2.1 Assume that s and n have been declared as integers. Explain in words what the purpose of the following segment of code is: (2)

int s = 0;

int n = 0; while (n <= 5)

{

s = s + n;

n++;

}

2.2 Explain the purpose of the following segment of code: (2)

int numbers[ ] = {11, 0, 15, 0, 16, 23};

int c = 0;

for (int i = 0; i <= 5; i++)

if (numbers[i] != 0)

c += 1;

Answer 1

#include<iostream>

using namespace std;

int main()
{
	//a)
	int s = 0;
	int n = 0;
	//Purpose of this code is increasing incrementing
	//After every iteration s increases by 1..2..3..4..5
	while (n <= 5)
	{
		s = s + n;
		n++;
		cout << "n= "<< n<< " s= " << s<< endl;
	}

	//b)
	int numbers[] = { 11, 0, 15, 0, 16, 23 };
	int c = 0;
	//Purpose of this code is count of nonzero elements in an array 
	for (int i = 0; i <= 5; i++)
		if (numbers[i] != 0)
			c += 1;
	
	cout << "The number of nonzero c = "<<c;
}
