C should be left alone. It does what it needs to do for a systems

Almost no use uses it for applications any more and sophisticated
processing
using complex types for example are far better done in C++.

C99 can naturaly do numeric computing that previously was done using
Fortran 77. Offical C++ has no VMT. C++ mechanizms look nicer,

Try to compile this in a C++ compiler:

#include <stdlib.h>
#include <stdio.h>

int main() {
void *p = malloc(sizeof(int));
int *ip = p;
free(p);

You are using a combined C and C++ compiler in C mode, and it compiles
the C program as C. In that sense, most C++ compilers are also C
Err yes! Thats the whole point!!
