755960 2009-03-13 01:43:00 Hi all. I'm looking for a program to generate random words/strings. I've been googling, but haven't found much freeware. It has to be able to generate words to a filter (eg: llnnllnn = ah78yr88) en masse. Can anyone suggest anything? Thanks. ubergeek85 (131)

755962 2009-03-13 01:53:00 I'll admit, it's a bit hard to explain. I'm after a program that generates lots of random strings, can save thise strings to a text file, and I can change how it generates the string, eg the first char has to be a letter, second char has to be a number, etc.

Make sense? :sleep I almost put myself to sleep. 		ubergeek85 (131)
755963 2009-03-13 02:16:00 I could write that in my sleep. Is Linux-based OK? Erayd (23)

It is a random generator. There are quite a few online generators.

Save to an html file and run in your browser.
Then you have to copy/paste words into your text file. 		dyewitness (9398)
755966 2009-03-13 04:17:00 And here's a C one. First argument is the number of strings to generate, second argument is the format code (l=letter, n=number, s=symbol), third argument is an optional filename. If you don't specify a filename, it'll print the strings to the console instead.
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>

int main(int argc, char **argv) {
//vars
long i, limit;
int i2;
const char *letters = "abcdefghijklmnopqrstuvwxyz";
const char *numbers = "0123456789";
const char *symbols = "~!@#$%^&*()_+=-`{}|[]\\:\";'<>?,./";
char *outstr;
FILE *fh;

//count args
if(argc < 3) {
printf("Not enough arguments!\n");
exit(EXIT_FAILURE);
}

//open file handle
if(argc > 3) {
fh = fopen(argv[3], "w");
if(fh == 0) {
printf("Unable to open file!\n");
exit(EXIT_FAILURE);
}
}

//seed prng
int seed = (int) time(0);
srandom(seed);

//generate strings
limit = strtol(argv[1], 0, 10);
printf("Generating %ld random strings...\n", limit);
outstr = malloc(sizeof(char) * (strlen(argv[2]) + 1));
outstr[strlen(argv[2])] = '\n';
for(i = 0; i < limit; i++) {
for(i2 = 0; i2 < (int) strlen(argv[2]); i2++) {
switch(argv[2][i2]) {
case 'l':
outstr[i2] = letters[(int) (random() % strlen(letters))];
break;
case 'n':
outstr[i2] = numbers[(int) (random() % strlen(numbers))];

//print to console if no filename given, otherwise write to file
if(argc < 4) {

dyewitness, are you are aware that you can specify an array all in one go? Just use new Array('a', 'b', 'c'); etc. 		Erayd (23)

Yes. 		dyewitness (9398)
755968 2009-03-13 04:28:00 Yes.

Then why slow things down and add a ton of extra code by doing one letter per line?

Edit: You can access strings by index in javascript anyway, so you don't actually need to declare it as an array at all - just specify it as a string 'abcdefghi...', then access individual characters in the same way you would elements of an array. 		Erayd (23)
755969 2009-03-13 04:37:00 Heh, it's a javascript solution so it's going to be slow anyway compared to your C version, but has the benefit of no compilation and browser based

Having said that:
- 26 extra lines is hardly going to add much overhead
- it is a rush job, so coding style isn't high on the priorities
- I was going to do something else with it, but changed my mind, and the explicit array init just stayed as is
- it can always be refactored
- does it really matter? 		dyewitness (9398)
