+.SH The conversion specifier
+Character that specifies the type of conversion:
+.RS 0
+.B %d, %i:
+.RS 0
+For integers we use either 'd' or 'i', so the int argument is converted to signed decimal notation.
+.RS 0
+.B %s:
+.RS 0
+For strings we use 's', so the const char *argument is expected to be a pointer to an array of character type (pointer to a string).
+.RS 0
+.B %c:
+.RS 0
+To print a character.
+.RS 0
+.B %R:
+.RS 0
+To print the rot13 of a string.
+.RS 0
+.B %p:
+.RS 0
+To print the pointer data type.
+.RS 0
+.B %u:
+.RS 0
+To print an unsigned integer.
