Multiple sine periods with a specific fundamental frequency

I'm trying to make 5 periods of a SINE signal with fundamental frequency f=100Hz, sampled at frequency fs=20*f=2000Hz but unfortuately I don't know what is wrong.

%%Time specifications:
   Fs = 20;                   % samples per second
   dt = 1/Fs;                   % seconds per sample
   StopTime = 0.16;             % seconds
   t = (0:dt:StopTime-dt)';     % seconds
   %%Sine wave:
   Fc = 2000;                     % hertz
   x = sin(2*pi*Fc*t);
   % Plot the signal versus time:
   figure;
   plot(t,x);
   xlabel('time (in seconds)');
   title('Signal versus Time');
   zoom xon;

   %%Time specifications:
   Fc = 100; % fundamental
   Fs = 20*Fc; % sampling rate
   dt = 1/Fs; % sampling period
   StopTime = 5/Fc; % num periods * length of a period
   t = (0:dt:StopTime-dt)';     % seconds
   %%Sine wave:
   x = sin(2*pi*Fc*t);
   % Plot the signal versus time:
   figure;
   plot(t,x);
   xlabel('time (in seconds)');
   title('Signal versus Time');
   zoom xon

Optionally, maybe make t = (0:dt:StopTime) to get a full 5 periods
