Question

I am trying to initialize an array of bools like so:

bool FcpNumberIsOk[MAX_FCPS]={true};

but when I debug it, I only see the first element of the array initialized, the others are false. How can that be so? I am using Qt on ubuntu 10 and the initialization is done on a local array inside a method.

Ok thanks for your answers.

Answer 1

Because that’s the way array initialization works in C++. If you don’t explicitly give a value for each element, that element defaults to zero (or, here, false)

 bool FcpNumberIsOk[MAX_FCPS]={true, true, true, true /* etc */ };

Note that

 bool FcpNumberIsOk[MAX_FCPS];

Will set all values to false or have them set randomly, depending on where this is defined.
