Stupid question about arrays

[Tonwo]

I have this problem when I work with arrays,I want to create an array, and later I want to give values.


I know I can do this:

int a[2]={3,6};

but why I cant do this?

int a[2]
.
.
.
a={3,6};

[frequentguest]

because it's not correct C syntax...
[code]
a[0]=3;
a[1]=6;
[/code]
is the most simple way to do it, but there are dozens of ways of performing this behavior.

You need to give exact instructions on where you want each value to be stored. An array is a group of numbers that have a common reference but each location is considered to be an individual variable. Simply stating

a = {3,6};

doesn't say where you want each one to be placed. If you had an array

a[100]

and you wanted a value of 100 placed in location a[90] you would need to specify that it be placed there. You're wanting the program to 'assume' you want the numbers placed at the lowest location, in order. You can't do this. You need to specify, exactly, what you want to do with no assumptions allowed. You need to write:

a[90] = 100;

As with your example, you can declare:

int a[2];

Then stuff values into it:

a[0] = 3;
a[1] = 6;

That's just the way it is.
