Generating random strings

[cameliachristina]

How do you generate random strings in C?

Thank you.

Random strigs of letters?

A crude method would be to generate a random number between 0 and 25 and add it to the character constant 'A' to get a letter. Then store the letters sequencially in a string terminating it with a zero terminator when you have enough letters.

Banfa's method will give you nonsense words that are 'randomized', a.k.a. "SJAORYEBRK ".

If you mean randomly choose a word from a list of given words, generate a random number between 0 and the size of the list - 1, then select that word. For example:

string words[5] = {"Cat", "Dog", "Admin", "TheScripts", "Computer"};
int pos = rand() % 5;
cout << words[pos] << endl; // Randomly prints one of the above words

You will need to build your own list of words somehow.

EDIT: This code is for C++, you may have to use printf, etc for C

The idea is right, but you need to seed it.

#include <iostream>
#include <stdlib.h>
#include <time.h>
using namespace std;

int main(){
string words[5] = {"Cat", "Dog", "Admin", "TheScripts ", "Computer"} ;
srand ((unsigned int)time(NULL)) ; // seeds the random [object] generator
int pos = rand() % 5;
cout << words[pos] << endl; // Randomly prints one of the above words
}
