Trying to Learn C++?

I recently got the complete idiots guide to c++,but i feel as if the author does not explain things simply or in detail sometimes.I am having trouble with arrays,one command has been bugging me specifically.





I don't understand when getting an array to list its elements you have to use this command.


cout %26lt;%26lt; number[index];








index sets up the for loop.I know this,but could someone in simple details explain whats going on in this command?I'll probably be feeling stupid once you tell me.

Number is a array, number[index] is an element of the array. Simple.
Reply:To start you can store data in variables. Such as:





int x = 5;


cout %26lt;%26lt; x;





You can store one value in x. If you wanted to store more than 1 value in a variable you use an array. Think of it as a list or some container that you can put more than one item into.





int x[3] = {2,4,6}





Now 'x' is storing 3 values two, four, and six. To access them individually you have to specify which element in the array you want.





x[0] would be two


x[1] would be four


x[2] would be six





Notice how the first index is 0 and not 1. It is like this in most computer programming languages. KEY POINT x[0] is the first element! This also means that 3 would be fourth element. If you tried to cout %26lt;%26lt; x[3]; you would get an error because x does not have four elements.





To print out those values you use the variable index to access them:





int index = 1;


cout %26lt;%26lt; x[index];





in this case it would print out ... you guessed it! '4'
