Note: Element indices start at 0 and end at 5.

4. Another array

Here is an array called c that has 3 elements of type int.

The declaration is as follows.

int c[3];

Note: Element indices start at 0 and end at 2.

5. Initialized array

Here is an initialized array called p that has 4 elements of type int.

The declaration with initialization values as literals is as follows.

int p[4] = {2, 3, 5, 7} ;

Note: Element indices start at 0 and end at 3.

This array literal declaration is the same as the following code.

int p[4];
p[0] = 2;
p[1] = 3;
p[2] = 5;
p[3] = 7;
