I am having a hard time putting a string into an array.

The purpose of my program is to generate random strings. And I want those random strings generated to be placed on an array so I can access those strings again later.

char main()

{

    srand(time(NULL));

    char* rStr[9] = {0};



    int i;

    for (i = 0; i < 7; i++)

    {

        randomString(rStr, 8);    //This is the function that generates a 

                          //random string with 8 characters

        printf("%d---%sn", i, rStr);

    }   

}

The above code will produce 7 randomly-generated strings with 8 characters. But my problem is I want every strings generated to be placed on an array so I can call them or display them again.

I have tried this below:

char main()

{

    srand(time(NULL));

    char* rStr[9] = {0};

    int i;

    for (i = 0; i < 7; i++)

    {

        rStr[i] = randomString(rStr, 8);

        printf("%d---%sn", i, rStr[i]);

    }   

}

but my program would just crash.

EDIT:

int randomNumber(int min, int max)     //This function is responsible for 

                                       //the randomness of the string

{

    max -= min;

    return (rand() % max) +min;

}



char randomString(char *str, int randomCharCount)

{

    const char *charSet = "abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

    int i;

    for (i = 0; i < randomCharCount; i++)

    {

        str[i] = charSet[randomNumber(0, 35)];

    }

}

Your code has following problems

1. No return type for main().


2. You have to declare separate array for saving strings.

Try the following code :-

char main()

{

  srand(time(NULL));



  char rStr[9] = {0};

  // sStr is where the rStr are saved .

  char sStr[50][9];  // max 50 rStr

  int i;

  for (i = 0; i < 7; i++)

  {

    randomString(rStr, 8);

    strcpy(sStr[i],rStr);

    printf("%d---%sn", i, sStr[i]);

  }

 // some return value here.

return 0;

} 

Think you're looking for strcpy.

Initialising and then "pushing" to the array:

char stringarray[MAX_NUMBER_STRINGS][MAX_STRING_SIZE]; 

strcpy(stringarray[0], "blah");

Also main should return an int see valid options below for main:

int main(void);

or:

int main(int argc, char* argv);
