What is the difference between g++ and gcc?

Question

What is the difference between g++ and gcc? Which one of them should be used for general c++ development?

Answer 1

I was testing gcc and g++ in a linux system. By using MAKEFILE, I can define the compliler used by "GNU make". I tested with the so called "dynamic memory" locating feature of "C plus plus" by :

int main(){

int * myptr = new int;
* myptr = 1;
printf("myptr[0] is %i\n",*myptr);
return 0;
}

Only g++ can successfully compile on my computer while gcc will report error

undefined reference to `operator new(unsigned long)'

So my own conclusion is gcc does not fully support "C plus plus". It seems that choosing g++ for C++ source files is a better option.
