Bottom line is both C++ and Ada are used for mission critical systems. 
Also it is easy to write safe code in C++ just by using its high level 
facilities, with no overflows, not anything.


For example consider this simple bullet-proof code for string input and 
processing:


#include <iostream>
#include <string>

int main()
{
     using namespace std;

     string s;

     while(cin)
     {
         getline(cin,s);

         /*Do things with s */;
     }
}
