Pure Programmer
Project: Aligning Characters and Strings with printf()
Write a program that demonstrates the formatting of characters and strings using printf() and/or sprintf() style output. Your program should reproduce the output shown using the following variables:
- c1 = "C" (or 'C' in C++)
- c2 = "-"
- c3 = 51
- c4 = 80
- c5 = 0x4f
- s = "Boba Fett"
