In other words, the half-life of U-238 is 14 billion years.

Atomic nuclei are held together by an attraction between the protons and neutrons (called the nuclear force), which has to be greater than the electrostatic repulsion between the protons within the nucleus in order for the nucleus to remain stable.

Decay happens spontaneously at any time when the electrostatic repulsion is greater than the nuclear force that holds the nucleus together.

Many elements have isotopes that are unstable because they have too many neutrons to be balance by the number of protons in the nucleus.

Each of these unstable isotopes has its own characteristic half-life, which is independent of almost any outside influence including the physical state, temperature, or pressure in which the nucleus finds itself.

Some half-lives are billions of years long, as with U-238, while others are shorter than a second.

I get 2 errors when I try to compile my program, the errors happen in my implementation file: error C4716: 'Dating Info::set Male Sex' : must return a value. Maybe you should change the return type to void, and make sure you do the same thing to those declarations in the header file.
