Thread: pls help in writing a program

Hi,


Pls help.Iam trying to write a program that searches the my hard drive to find a .cpp and reads the lines in the .cpp file

For example if user enters the string like c:bsb77/programs it has to find the .cpp files and read the file and count the lines in the cpp file.

Is there any standard fuctions that i can use for searching the hard dribve for a string .


Thanks

Travsersing a directory tree is OS/compiler specific

Searching for a fixed string in a file is standard - use the strstr function

Thanks Salem ! I will check the URLS !

I just looked at the program.Iam running this on UNIX>when i compiled my program iam getting many errors like dir.h not found.

struct ffblk finder not found ... can you pls tell me whether the walker is good enough to use in UNIX ?

Thanks

This is what i have as my program :

#include <iostream.h>
#include <dir.h>
#include <string.h>

#define ALL_ATTS ( \
FA_DIREC | \
FA_ARCH )

void walker ( char *path ) {
struct ffblk finder;
unsigned int res;

for ( res = findfirst ( "*.*", &finder, ALL_ATTS );
res == 0;
res = findnext( &finder ) ) {
if ( strcmp(finder.ff_name, ".") == 0 ) continue; // current dir
if ( strcmp(finder.ff_name, "..") == 0 ) continue; // parent dir

// if its a directory, examine it
// else compare the filename with the one we're looking for
if ( finder.ff_attrib & FA_DIREC ) {
char newpath[MAXPATH];
strcpy( newpath, path );
strcat( newpath, "\\" );
strcat( newpath, finder.ff_name);
chdir( finder.ff_name );
walker( newpath );
chdir( ".." );
} else {
if ( strcmp( finder.ff_name, "words.txt" ) == 0 ) {
printf( "Found!!!" );
}
}
}
}

int main ( ) {
char *root = "\\";
chdir( root );
walker( root );
return 0;
}

Then you need the opendir / readdir / closedir functions, and the stat() function (in sys/stat.h) to determine whether the current name is a file or a directory.

This example is for M$ operating systems
