This is a Simple C++ code for a converter program that converts energy into mass according to the famous equation from greatest scientist Albert Einstein. E= MC2
Input energy in MeV( Mega electron volt), GeV( Giga electron volt) or in Tev( Tera electron volt).
You can use visual c++ compiler for compiling and running program. You can find the Source code below. if you are using Borland turbo C++ don’t use “using namespace std;” and insert .h extension for iostream, iomanip header files. Moreover, it will not support “system(“CLS”);” and replace it by “clrscr();”
E= MC2: –
E = Energy
M = Mass
C = speed of light in vacuum (299792458 m/s)
Let’s imagine the practical use of this equation. Consider just a stone, which weigh 250g. If you convert it completely into energy, then the total energy from the mass;
E = 0.250(kg) x 89875517873681764 (c x c)
= 22468879468420441 J
