Question

Write a function template named maximum. The function takes two values of the same type as its

 

arguments and returns the larger of the two arguments (or either value if they are equal). Give

 

both the function declaration and the function definition for the template. You will use the

 

operator < in your definition. Therefore, this function template will apply only to types for

 

which < is defined. Write a comment for the function declaration that explains this restriction.
