    Red face Beginner: Help me compile this program

    Hello, I'm new to C programming, I came across a question asking to a compile a program, I dont know how to go about doing it, if anyone can write the code so I can learn from it, would be greatly appreciated.

    Here's how it goes:

    Build a simplistic C compiler (Filename: assign1.c)

    The program will perform "one pass" of a C-source file (.c) and produce a listing file (.list). A "pass" is the sequential reading of the C-source file, one line at a time, from top to bottom. Each line read from the C-source file will be written in sequence to the listing file, prepended by the line number and colon.

    Example: 1: #include <stdio.h>
    2: int main(int argc, char *argv[])

    At the bottom of the listing file, the program will write the following data concerning the "compiled" C-source file:
    • The total number of lines in the C-source file
    • The total number of occurrences of each of the following reserved words ( "int", "float", "double", "for", "while", "if")
      • Requirement: Your method for checking all reserved words must be extensible; i.e. we should easily be able to add more words without major changes in your code.
      • Bonus: The occurrences must not occur within comments.
      • Bonus: Recognize and act upon #include
    Finally, the program will write any/all "compiler errors". In our simplistic version of a compiler, the only error you are responsible for finding is the number of unmatched curly brackets.

    As input, the program requires the name of the C-source file and the desired name of the output listing file. These two input variables are to be provided by the command-line arguments.

    Start by implementing the "total number of lines in the C-source file" feature.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Actually, start by reading our homework policy. We help people find and fix problems in code they've written, we don't do their homework for them.
