       printf("------------------------------------------\n");   
       printf(" 2 to power n       n       2 to power -n\n");   
       printf("------------------------------------------\n");   
       p = 1;                                                      
       for (n = 0; n < 21 ; ++n)    /* LOOP BEGINS */
{ if (n == 0) p = 1; else p = p * 2; q = 1.0/(double)p ; printf("%10ld %10d %20.12lf\n", p, n, q); } /* LOOP ENDS */
printf("------------------------------------------\n"); } Output ----------------------------------------------- 2 to power n n 2 to power -n ----------------------------------------------- 1 0 1.000000000000 2 1 0.500000000000 4 2 0.250000000000 8 3 0.125000000000 16 4 0.062500000000 32 5 0.031250000000 64 6 0.015625000000 128 7 0.007812500000 256 8 0.003906250000 512 9 0.001953125000 1024 10 0.000976562500 2048 11 0.000488281250 4096 12 0.000244140625 8192 13 0.000122070313 16384 14 0.000061035156 32768 15 0.000030517578 65536 16 0.000015258789 131072 17 0.000007629395 262144 18 0.000003814697 524288 19 0.000001907349 1048576 20 0.000000953674
