Overview

TBB

Is a template library developed by Intel to provide methods to facilitate parallel programming. This is done by dividing a computation into tasks that can be scheduled to run in parallel threads on multi-core processors
Threading Building Blocks includes algorithms, concurrent containers, locks and memory allocation tools.
TBB is designed to work with any C++ compiler.

#include <tbb/tbb.h>

blocked_range<int> range0(0 ,40);
for (auto i = range.begin(); i != range.end(); i++) {
	 b[i] = 2 * a[i] + b[i];
}

STL

The Standard Template Library also extends useful functionality, including generic data structures, containers, iterators and algorithms that can be used to write clean efficient code.
The person who in 1979 was initially interested with ideas of generic programming, his work at AT&T and Bell Laboratories eventually lead to a proposal to the ANSI/ISO for the standardization of STL into the C++ standard.

#include <iostream>
#include <vector>
int main () {
  std::vector<int> myvector;
  for (int i=0; i < 6; i++) myvector.push_back(i);

  for (std::vector<int>::iterator it = myvector.begin(); it != myvector.end(); ++it)
    std::cout << ' ' << *it;
  std::cout << '/n';
}

Comparison

Both libraries use C++ templates to provide generic programming structures. The libraries do overlap when it comes to the functionality they provide, however STL is designed to be more general use and TBB specializes on parallel programming with threads.
Iterators: Both libraries use random access iterators to ease navigation of containers. TBB follows the standard set by STL and the ISO C++ standard, but they also extend them so that tbb::iterator can be used safely in concurrent threads.
