String Padding in C

Question

I wrote this function that\'s supposed to do StringPadRight(\"Hello\", 10, \"0\") -> \"Hello00000\".

char *StringPadRight(char *string, int padded_len, char          


        

Answer 1

You must make sure that the input string has enough space to hold all the padding characters. Try this:

char hello[11] = "Hello";
StringPadRight(hello, 10, "0");

Note that I allocated 11 bytes for the hello string to account for the null terminator at the end.
