Variables of this type are able to store sequences of characters, such as words or sentences. A very useful feature! A first difference with fundamental data types is that in order to declare and use objects (variables) of this type, the program needs to include the header where the type is defined within the standard library (header ):

The tech community loves to throw around acronyms more than most. Two of the acronyms that may confuse discerning hardware and software purchasers are the terms are VAR and VAD. These stand for Value Added Reseller and Value Added Distributor, respectively. This blog aims to shed some light on the closely related, sometimes overlapping, tech

15. ++var is the pre-increment operator; it increments the value of var before evaluating the expression. Similarly, var++ is the post-increment operator; it increments the value of var after evaluating the expression. In the case of a simple loop, there is no difference between two, because the expressions ++var; and var++; both yield to the
a := 10 b := "gopher". a will be declared as an int and initialized with value 10 where as b will be declared as a string and initialized with value gopher. Their equivalents using = would be. var a = 10 var b = "gopher". = is assignment operator. It is used the same way you would use it in any other language.
When comparing a string with a number, JavaScript will convert the string to a number when doing the comparison. An empty string converts to 0. A non-numeric string converts to NaN which is always false. When comparing two strings, "2" will be greater than "12", because (alphabetically) 1 is less than 2.
1. Var — var is used to declare a variable. If we want to declare a variable that’s value can be change we should use the var. 10 2. Val- If we want to declare a read only variable we should use the Val. One of the important thing about val is we can assign to val at runtime. . 516 722 724 709 459 835 346 594
