char str[] = "how are you";
printf("%*.*s\n", 5, 8, str);

Output

how are

Expected output

Someone has idea how this can be done?

Answer 1

The characters in the string are indexed from 0, so the a is at index 4. By passing &str[4] to printf, the printf will start at the a, and print as many characters as specified by the precision.

printf("%.*s\n", 3, &str[4]);

Answer 2

You are specifying field width and number of chars to print. However, the string always starts from the pointer as passed, there is no "start offset" specifier, as that would be unnecessary. See here for the format specifiers.

For your code, that would be printf("%.*s", width, str + start)

Note that &str[start] is identical.

Answer 3

try using this code

printf("%.*s\n", 3, &str[4]);
