Visual Programming using Flowchart

Abstract

Nowadays a computer programming become the fundamental knowledge for people studying or working in a computer field, e.g. computer engineering, computer science, information technology, etc. Programmer not only considers the algorithm carefully but also performs the coding according to the syntax of programming language used. Therefore writing a computer program is a difficult task, especially for a beginner. In fact, a novice often uses a flowchart as a tool to help him summarize the idea into all necessary steps of solution, but this flowchart cannot be understood by the computer. It must be converted to the program by using some programming language and then be compiled and run. The visual programming using flowchart proposed in this paper allows the programmer to write the program in the format of flowchart, then compiles and run, without the coding step. There is no necessity to remember the syntax of any programming languages. It takes the benefits of easy-to-understand and easy-to-perform of the flowchart, whereas eliminates the weakness of a conventional programming, e.g. the requirement of remembering the syntax, the error in coding step. Furthermore, a debugging of program by the proposed system is straightforward and easy to discover the error. The proposed system could be used as a tool for teaching the basic concept of structural programming as well. Experimental results show the powerfulness, easiness, and user-friendliness of the proposed system
