Converting Files to HTML - Part 1

You may think that you can just copy a text file and paste it into a HTML file and with the standard tags and have no trouble. This may work some of the time, but there are some characters that cannot be used in the text of a HTML file. An example of this is < and >.

The program shown below reads the file in from STDIO and outputs it to STDOUT.

#include <windows.h>
#include <stdio.h>

int main()
{
int ch;
while((ch =getchar()) != EOF)
   {
   if((ch >='0' && ch<=';') || (toupper(ch)>='A' && toupper(ch)<='Z') || ch==10 || ch==13)
       putchar(ch);
   else printf("&#%d;",ch);
   }
}
