Build a program with AI

Direct a model to write C++ — and review the memory and type choices it makes on your behalf.

You will build

A small program produced under your direction.

You will learn

Why C++ output needs sharper review than scripting languages, the prompt, and what to check.

Prerequisites

A coding assistant. A C++ compiler to run it, or read along.

What you must understand to judge it

  • Types are explicit and fixed; a model picking int where it needs size_t or double is a real bug, not a style nit.
  • Prefer the standard library (std::vector, std::string) over manual new/delete — ask for it.
  • Every program enters at int main(); compile-then-run is the loop.

The prompt

Write a C++ program that prints the squares of 1 through 5.
Constraints:
- Modern C++ (C++17). Use the standard library, no manual memory management.
- A function square(int n) returning int.
- Range-based for loop over a std::vector.
- Compiles clean with -Wall -Wextra.
Output a single main.cpp and the command to compile and run it.
Paste into your assistant
