Const before or const after?
...ir C compiler parsed input from left-to-right and finished processing each token as it consumed that. Consuming the * token changes the state of the current declaration to a pointer type.

What is the purpose of a stack? Why do we need it?
...erts on the semantic analysis of their language, not on efficient register allocation of new chip sets.
Now suppose we do it the CIL way. How many CIL generators do you have to write? One per language. How many JIT compilers do you have to write? One per processor. Total: 20 + 10 = 30 code generato...
Convert object to JSON in Android

Is gcc 4.8 or earlier buggy about regular expressions?
...x_match.
Here is an approach that works like regex_match but using sregex_token_iterator instead. And it works with g++.
string line="1a2b3c";
std::regex re("(\\d)");
std::vector<std::string> inVector{
std::sregex_token_iterator(line.begin(), line.end(), re, 1), {}
};
//prints all match...
Where does Java's String constant pool live, the heap or the stack?
...is in the runtime constant pool. The runtime constant pool memory area is allocated on a per-class or per-interface basis, so it's not tied to any object instances at all. The runtime constant pool is a subset of the method area which "stores per-class structures such as the runtime constant pool,...
