That's the right idea, however I would suggest a slightly more elegant version:

for(voltage = init_voltage; voltage <= end_voltage; voltage += increm_voltage)
  {
    puts("Table Heading"
         "------------------------------------");

    for(res = init_res; res <= end_res; res += increm_res)
      {
        printf("   %f             %f            %f   \n", voltage, res, voltage / res);
      }

  }

The name [incode]init_res[/incode] is suggestive of a constant or parameter, something you don't want to destructively modify -- indeed, doing so caused your problem. It also doesn't represent the physics expression very well (init_voltage should mean initial voltage, not present voltage).

Assigning a variable ([incode]voltage[/incode] or [incode]res[/incode]) in the loop is handier since you don't have to manually reset anything, and it's just more readable.

All I needed was a break (as in time away from the computer) . You can compare the two if you are interested.

The bad one : The good one

Basically, I added another var that held the original value of init_res, and after the inner most loop finished, it would reset init_res.
