Array outputs wrong variable

[raisetheroof00]

I'm currently learning about arrays, and tried experimenting with it in the compiler- and when I run it, it outputs the wrong variable (it's supposed to output '100', but outputs '212'- which is from a different variable). Any help would be appreciated.

#include <iostream>
using namespace std;
int main()
{
	int outTemp_1 = 100;
	int outTemp_2 = 32;
	int inTemp = 212;
	
	int testing[1] = {outTemp_1};
	
	cout << testing[1] << endl;
	return 0;					
}

Output terminal:
212

Hello raisetheroof00,

Lines 9 and 11 refer to an array, but where did you define the array before you used it?

I think what you are wanting is:

#include <iostream>

using namespace std;

int main()
{
	int outTemp_1 = 100;
	int outTemp_2 = 32;
	int inTemp = 212;
	
	int testing[1] = {outTemp_1};  // <--- (1) defines the size of the array.
	
	cout << testing[0] << endl;  // <--- (0) is the first and only element of the array.
	
	return 0;					
}

Line 11 defines an array with a of size of 1.

On line 13 when you say testing[1] this is one past the end of the array because the array starts at element (0) zero not (1).

Making this one change on line 13 the output is:

100

Oh no, I forgot that arrays started at 0 and not 1. Silly mistake.

Thank you!

Will be taking this question down soon.
