I have a list of 30 names from txt file. it also include nick name, club, and points. i want to randomly split the names into 6 groups of 5 per-group. Im very new with c programming, please help me.

#include <stdio.h>
#include <stdlib.h>

#define p printf
#define s scanf

FILE *tf;

struct listName
{
    char name[100];
    char nickname[50];
    char club[50];
    int point;
};

int main()
{
    struct listName ln[30];

    //open file to read
    tf = fopen("ListnamePlayer.txt","r");

    int i;
    //read data from file
    for(i=0;i<30;i++)
    {
        fscanf(tf,"%[^\n]\n",ln[i].name);
        fscanf(tf,"%[^\n]\n",ln[i].nickname);
        fscanf(tf,"%[^\n]\n",ln[i].club);
        fscanf(tf,"%i\n",&ln[i].point);
    }

    //print data from file
    p("\n\n");
    p("*****************************************************************************************\n");
    p("| No |                Name                           Nickname       Club      Points    |\n");
    p("*****************************************************************************************\n");
    int j=1;
    for(i=0;i<30;i++)
    {
            p("| %2i.| ",j++);
            p(" %-45s ",ln[i].name);
            p(" %-10s ",ln[i].nickname);
            p(" %-10s ",ln[i].club);
            p(" %-5i    |\n",ln[i].point);
            p("-----------------------------------------------------------------------------------------\n");
    }
    fclose(tf);
    return 0;
}
