Misc C++ Tips

This section shows you different C++ programing tips. Tip1. Properly define your functions (methods) within your classes ---------------------------------------------------------------------------- If you have the following code: #include <iostream> using namespace std; class address   {     public:       void show_address(void) { cout << street << ' ' << number << endl; };       address() {  number = 0; street = new char [500]; };       address(char* street, int number)         {           address::street = new (nothrow) char [500];           strcpy(address::street, street);           address::number = number;         };       ~address() { delete street; }     private:       char* street;       int number;   }; int main(void)   {     address addrs("Main Street", 10);     addrs.show_address();   } And when you try to compile you get the following warning: test1.cc: In function 'int main()': test1.cc:25: warning: deprecated conversion from string constant to 'char*' Then it means the compiler warns you that your function is allowed to modify memory, and it should not. So instead of       address(char* street, int number)     you should have:       address(const char* street, int number)
