I have a file I need to open and find "0x.xx", where x.xx is a wildcard that is all numbers.
I need to replace "0x.xx" with "01.00". The "0x.xx" is more than "01.00". Could someone give me some code to do that and then output the entire file into a new file?
Cannot use string.
I'm currently using the following code to store the information I'm looking looking for in a variable, but I need to change it and reinsert it into the file. It's untested atm, but should work.
Code:FILE *fp = fopen ("/somepath/file.DAT", "r" ); if ( fp != NULL ) { char line [ 16 ]; if (fgets ( line, sizeof line, fp ) != NULL) { sprintf(Versioninfo, "%s", strstr(line, "0")+1+strstr(line, ".")+2+strstr(line, "00")); // 0x.xx00 (IE: 01.1300) return 0; } else { return -2; } } else { return -1; }

Is this part of some automatic version numbering when building your software?
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.
