Project: Aligning Floating Point with printf()
Write a program that demonstrates floating point formatting using default (most compact), fixed point and exponential formats using printf() and/or sprintf() style output. Print using no precision, precision of 2 and a field width of 10 with precision 2. Your program should reproduce the output shown using the following variables:
- π = 3.141592653589793
- 𝑒 = 2.718281828459045
- avogadro = 6.0221412927e23
- electron_mass = 9.1093821545e-31
