Step 1 of 6
Declare and index
An array is a fixed-size row of values of the same type, stored next to each other in memory.
int ammo[3] = {30, 20, 7};
printf("%d\n", ammo[0]); // 30, indexes start at 0
ammo[2] = 8; // change the last one
An array of size 3 has valid indexes 0, 1, 2. ammo[3] is out of bounds. C won't stop you, and the result is undefined behaviour.
Your turn: print the first and the last element of the array.
