[resolved] can you spot the problem with my newbie code
I've been bashing at this for a while, and i got rid of all the compile errors, except it crashes when i run it (doh!). right down the bottom of the code is a getchar(), after i hit enter to pass it is when it crashes. I'm pretty sure the error is in the readline function - befroe i added the funtion it worked.
The code is probably riddled with syntax errors and dumb newbie mistakes - I'm normally a vb programmer. So please, criticism of programming style is welcome too.
Oh, I have to do all this in basic C (ANSI C if possible) - it has to run in dos, or at least a command shell.
Code:
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#define SIZE 80
char *readline(char *buff, FILE *fpin);
int main(void)
{
FILE *fpin, *fpout;
char buff[SIZE];
long lcounter;
fpin = fopen("in.txt","r"); /* open for reading */
if( fpin == NULL)
{
printf("cannot open in.txt\n");
exit(1);
}
fpout = fopen("out.txt","w"); /* open for writing */
if( fpout == NULL)
{
printf("cannot open out.txt\n");
exit(2);
}
for(lcounter=0;lcounter<=62;lcounter++)
{
fgets(buff,SIZE,fpin);
}
// main file reading loop
while(readline(buff,fpin)!= NULL)
{
fputs(buff,fpout);
}
//finished, close files
fclose(fpin);
fclose(fpout);
return 0;
}
char *readline(char *buff, FILE *fpin)
{
char newpagecheck[24];
char *fgetsret;
//_strnset( newpagecheck, " " , 23 );
fgetsret = fgets(buff,SIZE,fpin);
strncpy(newpagecheck,(buff+42),23);
newpagecheck[24] = '\0';
printf("line: %s",buff);
if (newpagecheck=="Department of Education")
{
fgetsret = fgets(buff,SIZE,fpin);
printf("yay");
}
getchar();
return fgetsret;
}
cheers. did i mention that you guys here are the coolest?
