In ISO C99 you can give the elements in any order, specifying the array indices or structure field names they apply to, and GNU C allows this as an extension in C90 mode as well. This extension is not implemented in GNU C++. To specify an array index, write ‘[index] =’ before the element value. For example,Expressions. An expression is a sequence of operators and their operands, that specifies a computation. Expression evaluation may produce a result (e.g., evaluation of 2+2 produces the result 4 ), may generate side-effects (e.g. evaluation of printf("%d",4) sends the character '4' to the standard output stream), and may designate objects or ...
