We'll go over how to use printf() and fprintf() functions to generate useful and attractive reports including strings, integers, floats and doubles on Windows and Linux.

You will also see how to generate random test data to test your report after you have designed the report. Something you'll definitely do in your career.

Print codes/data types for use with printf():
- String: %s
- Unsigned Integers: %d
In octal format: %o
In hexadecimal lower case format: %x
In hexadecimal upper case format: %X
- Floating Point Numbers: %f
- Specifying the number of fractional digits: .n
Example: printf("%.2f", someNumber);
- Scientific Notation: %e (lower case e), %E (upper case E)
- Width of the data to print: %nType
Example printf("%12d", someNumber);
- Left justification: %-nType
Example printf("%-12d", someNumber);
- Printing the percent symbol: %%
