8.4 Basic Computer Engineering

8.3 ACCESSING VALUES OF AN ARRAY

As discussed earlier, the array elements can be individually referenced by Array_name and index.

Thus, elements are accessed through loop to read or modify values. Program 8.1 illustrates the process of

initializing and accessing an array.

The syntax is Array_name[index]

So, for example, to set the third element as 66, we may write:

marks[2] = 66 ;

To assign value of the third element of marks to a variable called p, we could write:

int p = marks [ 2 ] ;

Attempting to access a non-existent array element (e.g. marks[ 5 ] in Program 8.1) does not cause

compilation errors but leads to ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
