What you post will work.

Obviously, you need 'array1' declared, and large enough to hold the values. So:

int array1[4];

Remember all your lines need the ';' terminator.
You could also declare the array to be 'pre-filled' with the numbers, as:

int array1[] = {16,25,20,4};

The compiler will automatically make the array large enough to hold the number of values declared.
These values will be stored into the array, when the code starts, but the numbers can then be changed as needed.
This differs from a 'constant' array, such as:

const int array1[] = {16,25,20,4};

Which will contain the same numbers, but they then cannot be changed.

Best Wishes

what if numb1, numb2, numb3, & numb4 are integer values that varies depending on the program... say a counter that changes depending on a condition... wen a condition are met then the current integer value of numb1, numb2, numb3, & numb3 should be stored in an array.

Can u comments on this.

Thnx

You can change the array of interers from 8 bit to 16 bit but only at compile time.

Int8 Buffer[8];
or
Int16 Buffer[8];

Code:

if (condition)
{
array1[0] = numb1;
array1[1] = numb2;
array1[2] = numb3;
array1[3] = numb4;
}
