It _should_ be easier to read. But in my experience it isn't.
The problem is that C++ is a very complex language. It's
difficult to determine by inspection what a piece of code does
because of all the overloading/templating/whatnot that C++
allows. There are too many times when a line of code doesn't
do what it appears to do to a reader.
Just the problem of deciding whether "foo" is a local, global,
or instance variable can be difficult for a human inspector.
Throw in some cpp tricks and it's hopeless. I know that C++
was supposed to eliminate the need for cpp, but it still gets

In my experience, C++ is too complex a language to allow for
practical, thorough inspection of source code. And since C++
still allows you to generate dangling pointers, memory leaks,
indexes out of range and whatnot, you _need_ to inspect source
code to detect many of those types of problems.
C also allows you to generate those problems, but the language
is simple enough that inspection is a practical exercise.
OTOH, Python (or Modula-3 or Smalltalk or ....) won't _allow_
you to generate a pointer to nothing or index off the end of an
array. Additionally, they're far simpler languages than C++, so
other types of errors are easier to spot.
