【简答题】
In order to solve a computational problem, its solution must be specified in terms of a sequence of computational steps, each of which may be performed by a human or a digital computer. If you want to solve the computational problem with a computer, you should learn how to program. The task of developing programs for the solution of computational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficult to work out otherwise. So programming is breaking a task down into small steps. Programming is sometimes contrasted with coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of a program is sometimes referred to as code, and lines of program text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications prepared by others. What's actually involved in programming - the actual process of writing programs? Here's a quick overview of the process: • Write a program. • Compile the program. • Run the program. • Debug the program. • Repeat the whole process until the program is finished. 1. If you want to solve the computational problem with a computer, you should learn how to ____. A. calculate B. program C. add D. subtract 2.Computer programming is the process of planning and creating a sequence of _____ for a computer to follow. A. steps B. process C. lines D. graphics 3. The term coder is used to describe _____. A. machine B. computer C. keyboard D. person 4. In order to solve a computational problem, you can let a person or a _____ to do it. A. machine B. computer C. Keyboard D. mouse
