    Text Formatting Program Help

    Hello,
    I am working on a program that takes text and modifies it so it can be printed. It adds lines between paragraphs, page numbers, etc.

    I am having problems modifying the actual text. I have an outline:
    Code:
    #include <stdio.h>
    
    void txt2prt(char *input, char *output);
    char *header(int page);
    char *footer(int page);
    
    int main(int argc, char *argv[]) {
        char *infile = "infile.txt";
        char *outfile = "output.txt";
        
        //argc counts executable as 1 arg
        if( argc == 2 ) {
            infile = argv[1];
        }
        
        if( argc == 3 ) {
            infile = argv[1];
            outfile = argv[2];
        }
        
        txt2prt(infile, outfile);
        
        return 0;
    }
    
    void txt2prt(char *input, char *output) {
        int currentPage = 1;
        while(*input){
    		do(*input
    
        //While read from infile, do header, parse and print and footer
    }
    
    char *header(int page) {
        char *retStr;
    
        //ADD HEADER AND PAGE NUM TO retStr
        
        return retStr;
    }
    
    char *footer(int page) {
        char *retStr;
        
        //ADD FOOTER AND PAGE NUM TO retStr
        
        return retStr;
    }
    I was going to use a series of condition statements to apply the various indents and blank lines, etc. I was just wondering how I would go about modifying the input text (getting the input, and outputting something else)

    Cheers,
    Larph

    Well the first step would be to write a program which simply copies the input file to the output file one line at a time.

    Then you can add things like
    - a count of the lines read, and then work out where page boundaries go (for header and footer).
    - work out where paragraphs are (what is your assignment specification for this?), then add blank lines.

    Incremental development - begin by working out what series of small steps will get you to your goal.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
