is my code ok?

Question

Hello everyone,
One of the questions in the exercises from the first lesson of the C++ arrays chapter in Sololearn was the following:

**PRACTICE EXERCISE**
**Alphabet**
The given code declares an array that holds the letters of the English alphabet.

**Task**
Take a number as input and output the letter from the array that corresponds to that index.

To solve this problem, I wrote the following code:

```cpp
#include <iostream>
using namespace std;

int main() {
char letters[] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'};
int num;
cin >> num;
cout << letters[num];
}
```

My code was accepted and it worked correctly!
It was surprising to me that my code was accepted and worked as expected!
I would appreciate it if you could let me know whether I solved the problem exactly as intended by the question, or if it needed to be solved in a different way.

Thank you all!

Answer 1

As a beginner level mohammadhoseinmohebian's solution is perfect no change need to be done here. Just keep going and continue learning.

Happy coding!

Answer 2

would work in constraint 0<= num < 26
think what if i entered 35 ...

a more c++ way of doing it would be using
std::array

and you can either bound check using .at() or assert 🥲 ( just cuz you asked )

Answer 3

mohammadhoseinmohebian ,

this kind of question is not meant to be posted in the `q&a` section.
`q&a` is for coding related issues.

post and present your code in the ` community section` feed instead.
