C Programming?

Im trying to find uniqeness for my program that I have and I dont know how to write it...











#include %26lt;stdio.h%26gt;


#include %26lt;stdlib.h%26gt;





int gen( int letter )


{





int x = rand()% 14 + 1 + 15* letter;


return x;





}








int main()


{


int i;


int j;


int A[5][5];


int letter;


int unique;


FILE *card;


srand(time(0));








card = fopen("card", "w");


for (i = 0; i %26lt; 5; ++i)


{


for(j = 0; j %26lt; 5; ++j)


{


A[i][j] = gen(i);


}


}





A[2][2] = 0;





printf("B\tI\tN\tG\tO\t\n");





fprintf(card,"B\tI\tN\tG\tO\t\n");





for (i = 0; i %26lt; 5; ++i)


{ printf("%d\t%d\t%d\t%d\t%d\n", A[0][i], A[1][i], A[2][i], A[3][i], A[4][i]);


fprintf(card, "%d\t%d\t%d\t%d\t%d\n", A[0][i], A[1][i], A[2][i], A[3][i], A[4][i]);


}





fclose(card);





return 0;


}

C Programming?
what is your problem here? is it about getting different random values?





if so, then time() returns a time_t (time type); you need to convert it to an unsigned int then pass to srand().
