Document Summary

Programming is specifying the structure and behavior of a program, and testing that the program performs its task correctly and with acceptable performance. Assembler was the first high level programing language but was processor dependent. Java, c, c++, c#, php, visual basic, python, ruby, javascript, basic, cobol, Variable is basically the location in the memory. Variable hours is created as an integer and is assigned to 40. A text editor is used to edit and save a java source file. A compiler is a program that translates source code into an executable form. A compiler is run using a source code file as input. Steps of a compiler: run using a source code file as input, translate source code into executable files containing machine code, the java compiler translates a java source file into a file that contains byte code instructions. Byte code instructions are the machine language of the.
