A token in C++, and in many other computer languages as well, is the largest set of characters in the source code that meets the criteria of a single language element. Often, tokens are separated by white space, but if the context is clear, this is not required. The expression a=b+c, for instance, contains 5 tokens, a, =, b, +, and c. The expression a = b + c is identical in meaning. The "largest set" rule can be shown with the example a=b+++c. The tokens are a, =, b, ++, +, and c. This expression means to add b and c, store the result in a, and then increment b.
All arithmetic, logical operators are operators in c tokens. As: +, - , ++, --, %, &&, &, >>, << etc.
