Integer Types

#include <limits>   // holds constants for int size, e.g. INT_MAX, INT_MIN, etc..

sizes (dependent on compiler used)

short int - 16 bits int - 32 bits long int - 64 bits

sizeof(int) returns number of bytes used

Some compilers allow long instead of long int, the same also applies to short in place of short int

Exceptions

CoP Thought: Only use them for states from which your can't recover from. (e.g. unable to allocate enough memory) (Or alternatively - use for all error handling and keep error handling separate from main code)

void mightGoWrong() {
    bool error = true;
    if(error) throw 8;
}
asd
int main() {
    try {
        mightGoWrong();
    } catch(int e) {
        cout << "Error code: " << e << endl;
    } catch(std::string & e) {
        cout << "Error message: " << e << endl;
    } catch(char const * e) {
        cout << "Error message: " << e << endl;
    }
}

Can throw anything as an exception - including primitives, error strings and objects. (however you do need to catch the correct type)
