Question

Write a literal corresponding to the floating point value one-and-a-half.

Answer 1

1.5 In C or C++, a floating point literal is nothing more than a sequence of decimal digits with either or both an decimal point, or an exponent with optionally a type specifier. The value could be any of the following: 1.5, 1.5e0, 0.15e1, 15e-1, etc.
