Hope that helps When printf parses the format string it prints the characters that are not format specifiers as they are.
So when it parses "Programming Language" it just echoes each character.

What is the purpose of the h and hh modifiers for printf?

hop of those help? One possible reason: for symmetry with the use of those modifiers in the formatted input functions? I know it wouldn't be strictly necessary, but maybe there was value seen for that?
Although they don't mention the importance of symmetry for the "h" and "hh" modifiers in the C99 Rationale document, the committee does mention it as a consideration for why the "%p" conversion specifier is supported for fscanf() (even though that wasn't new for C99 - "%p" support is in C90):

I hope this helps you . I need help on this exercise from C Primer Plus. , Here is one way to do it:
code :

int main()
    char a[40];

    printf("Enter your first name: \n");
    printf("[%-*s]", (int)(3 + strlen(a)), a);

printf("%*s", 10, "Hello");
printf("%-*s", 10, "Hello");

I think the issue was by ths following , According to Wikipedia:
Is it illegal to use the h or hh length modifiers when the corresponding argument to printf was not a short / char?

hop of those help? The printf family of functions provide a series of length modifiers, two of them being hh (denoting a signed char or unsigned char argument promoted to int) and h (denoting a signed short or unsigned short argument promoted to int). Historically, these length modifiers have only been introduced to create symmetry with the length modifiers of scanf and are rarely used for printf. , The standard specifies:

around this issue This is undefined behavior, read the documentation.
Basically passing a parameter that has a different type than the one expected by the specifier is considered undefined behavior by the standard.
