| Abstract: | Compiler can translate source code into object code, which plays an inestimable role in the development of application pro- grams. In teaching, expression evaluation and sign derivation have vital important roles in understanding the working principle of com- plier. This paper discusses the method of expression evaluation and sign derivation by similar C language and it has promotion effects in teaching and research. |
