Getting Blank Graph as Output

I'm getting blank graph for the following code.......

clc
clear all;

fc=154000;
fm=fc/10;
fs=100^fc;

t=0:1/fs:4/fm;
xc=cos(2*pi*fc*t);
xm=cos(2*pi*fm*t);
figure(1)
subplot(2,1,1)
plot(t,xc);
xlabel('time(sec)');
ylabel('amplitude');
title('carrier signal of 154 khz')
grid on;

fc=154000;
fm=fc/10;
fs=100^fc;
t=0:1/fs:4/fm;
xc=cos(2*pi*fc*t);
xm=cos(2*pi*fm*t);
figure(1)
subplot(2,1,1)
plot(t,xc);
xlabel('time(sec)');
ylabel('amplitude');
title('carrier signal of 154 khz')
grid on;

size(t)

ans = 1×2

1 0

size(xc)

ans = 1×2

1 0

fs

fs = Inf

If you are going to take 100^ something then you are going to overflow to infinity if the exponent is more than 154 (so 10^308 output)

Thank you very much. Resolved. It was typing error.
