This printf statement prints two strings: left aligned within a width of 25 characters and a substring with the specified length.
This “%-Ns” option prints the string in left aligned format in width of N characters.
The format “%.*s” is used to print a substring from a given string, where the length of the substring is passed along with printf call. The “*” in “.*” allows you to define the length at runtime. If the specified length exceeds the maximum length of the string, the entire string will be printed.
The “*” in format specifiers enable dynamic control of width and/or precision at runtime. “%.*s”,”%.*f”,”%.*e” formats dynamically control precision. “%*s”, “%*d”, “%*f” formats dynamically control width.
printf(“%-*.*s\n”, 10,4,”Hello world”); // left aligned width of 10 chars and prints 4 chars.
The format “%.Ns” prints up to N characters.
“%%”, “\\”, “\””, “\’” formats print “%”, “\”, “ “ “,” ‘ “.
Some size formats are: “%hd” for short int, “%zd” for sizeof() , “%td” for pointers differences
