Answer to Question #326496 in C++ for nickname

Question

Observe the following code:

 

const int SIZE = 3;

int nums[SIZE] = {1, 2, 3};

for (int i = 0; i <= SIZE; i++) { 

  std::cout << nums[i];

}

 

What is wrong with this code?

A: You cannot use constants with array definitions

B: The initialization list exceeds the size of the array

C: Should be i = 1 because you need to start with the first array element

D: Should be i < SIZE so that you don't access an array element that doesn't exist

Answer 1

#include<iostream>

using namespace std;

int main()
{
	const int SIZE = 3;
	int nums[SIZE] = { 1, 2, 3 };
	for (int i = 0; i < SIZE; i++)
	{
		cout << nums[i];
	}
	//D: Should be i < SIZE so that you don't access an array element that doesn't exist
}
