casting - C++ Cast increment cast - 


someobject* scratchpad[10000][33];

i want in 1 statement:

unsigned int index = (int) scratchpad[j][0];     scratchpad[j][0] = (someobject*) (index + 1);

i thought was:

unsigned int index = (unsigned int) ++((char*)scratchpad)[j][0];

but can't quite syntax right. i'm storing integer in first (0) sub-array index.

don't store integer in first sub-array index. store elsewhere. seriously. don't this.

but if you're absolute maniac who's goal make people hate you, works, on assumption unsigned int no bigger pointer.

unsigned index = ++reinterpret_cast<unsigned&>(scratchpad[j][0]);
