Too many input argument?

I am not sure what MATLAB means when there are too many input arguments. Specifically for this program, it says there is an error on line 21. I put asterisks on that line.

Response = 'Yes';
while (Response == 'Yes');

clc %This will clear the entire Command Window
clear %This will clear the all the values saved in the variables found in the Workspace

Change

UserProduct = input('\nThe product of %.0f and %.0f is\n', NearFirstInteger, NearSecondInteger___);

to

UserProduct = input( sprintf('\nThe product of %.0f and %.0f is\n', NearFirstInteger, NearSecondInteger) );

and likewise for the case where the user enters their own integers.
