There is tricky thing for deleting in vector loop. The erase method returns the next element after the one you just erased. So you can use that to continue in your loop. vector c; iterator i = c.begin(); while(i != c.end()){ if (i == something) { //i = i.erase(); i =...

Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for ...
