Hence, in abstract, Programming is a way to inform computers to do a selected task. They cannot often be expressed in easy instructions like adding 2 numbers, etc.
In static typing, all expressions have their types determined previous to when this system is executed, sometimes at compile-time. For instance, 1 and (2+2) are integer expressions; they can’t be handed to a perform that expects a string, or stored in a variable that is defined to carry dates. The time period semantics refers to the meaning of languages, as opposed to their kind . If the kind declaration on the primary line were omitted, this system would trigger an error on undefined variable “p” during compilation. However, the program would still be syntactically appropriate since type declarations provide only semantic information. Programming language evolution continues, in each industry and research. Current directions include security and reliability verification, new kinds of modularity …
