Question

I have a char byte that I want to convert to an int. Basically I am getting the value (which is 0x13) from a file using the fopen command and storing it into a char buffer called buff.

I am doing the following:

//assume buff[17] = 0x13

v->infoFrameSize = (int)buff[17] * ( 128^0 );

infoFrameSize is a type int that is stored in a structure called ‘v’.

The value I get for v->infoFrameSize is 0x00000980. Should this be 0x00000013?

I tried taking out the multiply by 128 ^ 0 and I get the correct output:

v->infoFrameSize = 0x00000013

Any info or suggested reading material on what is happening here would be great. Thanks!

^ is bitwise xor operation, not exponentiation.
