C Arrays

Store a fixed sequence.

On this page

The concept

An array groups values of one type. Its size is fixed and indexing begins at zero. Stay within the declared bounds.

#include <stdio.h>
int main(void) {
  int scores[] = {82, 91, 76};
  printf("%d\n", scores[1]);
  return 0;
}

Step / line	What happens	State after step	Output so far
	Create three consecutive int elements.	`scores = {82, 91, 76}`	—
	Index 1 selects the second element.	`scores = {82, 91, 76}`	91

How C processes this code

The C compiler produces a native program. Variables occupy memory, and execution enters main.
