In this project, you should implement a C interpreter. The supported input file should at least contain the following features:
(1) integer and floating-point data types: int, float.
(2) Statements for arithmetic computation. (ex: a = b+2*(100-1)) (3) Comparison expression. (ex: a > b)
(4) if-then-else program construct.
(5) printf() function with one/two parameters. (support types: %d, %f)
(6) scanf() function. (support types: %d, %f)
The following is a sample C program (input file):
1. void main()
2. {
3. int num;
4. float s;
5.
6. printf(“Please enter a number:”); 7. scanf(“%d”, &num);
8.
9. if (num > 10) {
10. s = 3 * (num + 3.14);
11. } else {
12. s = num * (num – 3.14);
13. }
14.
15. printf(“The result is %f\n”, s);
16. }
