Arrays and Strings

Core idea

Arrays store multiple values of the same type, and strings store text. These are useful once you already understand variables, conditions, loops, and functions.

Array example

#include <iostream>

int main() {
  int scores[4] = {85, 90, 78, 92};
  std::cout << scores[0] << "\n";
}

String example

#include <iostream>
#include <string>

int main() {
  std::string language = "C++";
  std::cout << "Learning " << language << "\n";
}

Revision points

• Arrays keep items in order.
• Indexing starts at 0, not 1.
• std::string gives you useful tools like length checking and concatenation.
• Loops are often used to read or print array values one by one.

What to remember

Use arrays for grouped values and strings for readable text data.

Next step

After this, you can move into more advanced C++ ideas like ownership and memory management.
