CCUCD Project 3-A Simple C Interpreter Solved

Description

 

 In this project, you should implement a C interpreter. The supported input file should at least contain the following features:

• integer and floating-point data types: int, float.
• Statements for arithmetic computation. (ex: a = b+2*(100-1)) (3) Comparison expression. (ex: a > b)
• if-then-else program construct.
• printf() function with one/two parameters. (support types: %d, %f)
• scanf() (support types: %d, %f)

 

The following is a sample C program (input file):

1. void main()
2. {
3. int num;
4. float s;
6. printf(“Please enter a number:”); 7. scanf(“%d”, &num);
8. if (num > 10) {
9. s = 3 * (num + 3.14);
10. } else {
11. s = num * (num – 3.14);
12. }
14. printf(“The result is %f\n”, s);
15. }

 

In your hand-in report, you need to have the followings:

• Describe the C subset supported by your interpreter.
• Give a set of testing programs which can illustrate the features of your interpreter. (at least 3 test programs)
• Use the “ANTLR” to help you develop your interpreter.
• You can use Java or other programming languages to write your interpreter. (Java is recommended)
• Please ensure your program can be executed under the mcore8 or
