In c++ when using printf() can you tell me all of the different variable types I can use, like %i, %f, etc.
Here's a list of all the format specifiers supported by the printf function in C++:

%d or %i - Prints an integer in decimal
%u - Prints an unsigned integer in decimal
%f - Prints a floating-point number
%c - Prints a single character
%s - Prints a string of characters
%x or %X - Prints an integer in hexadecimal format
%o - Prints an integer in octal format
%p - Prints a pointer address
%e or %E - Prints a floating-point number in scientific notation
%g or %G - Prints the shorter of %f or %e
%a or %A - Prints a floating-point number in hexadecimal scientific notation
%n - Writes the number of characters written so far to an integer pointer argument
%ld or %li - Prints a long integer
%lu - Prints an unsigned long integer
%lld or %lli - Prints a long long integer
%llu - Prints an unsigned long long integer
%h - Indicates that the following integer argument is short
%L - Indicates that the following floating-point argument is a long double

Note that all compilers or platforms may not support some format specifiers. The best way to ensure compatibility is to consult the documentation for your current compiler.
Can you give me some code examples of using printf format specifiers in C++?
