return value by reference from a sub-function

[anandkumar]

I have computed an array y[100] in a subfunction.

The value of y needs to be referenced in the main function.

Is it possible for me to pass the address of y[100] from the sub-function to the main function using the statement 'return(&y);' and reference y in main function using a pointer?

Is there any similar way to access the variables by reference in a sub-function?

If you created y as a local variable of the sub-function then no because when the function exits the variable is deleted.

You could declare the array in main and pass a pointer to it into the sub-function then the sub-function will work on the array in main.
