left shift operator - qsn

[aliasger.jaffer]

Hi,

I have an array A[10] of type short, and I want to left shift the value
in index 0 by four. I tried the following statement:

A[0] << = 4;

Unfortunately, I get the following error when I try to compile:
-- expected primary-expression before '=' token.

Any ideas/suggestions what i'm missing or doing wrong?

Thanks!

Ali

Get rid of the space between << and =.

A[0] <<= 4;

Beware of integer promotion when playing around with anything smaller than an
int.
