  1. #include < stdio.h >
    #include < sys/types.h >
    #include < time.h >

    int main()
    { int i;
    time_t t1,t2;

    (void) time(&t1);

    for (i=1;i<=10000;++i) printf("%d %d %d\n",i, i*i, i*i*i);


    (void) time(&t2);

    printf("\nTime to do 300 squares and cubes= %d seconds\n", (int) t2);
    printf("\nTime to do 300 squares and cubes= %d seconds\n", (int) t1);
    printf("\nTime to do 300 squares and cubes= %d seconds\n", (int) (t2-t1));

    getchar();
    return 0;

    }
