C++: How do I dereference multiple characters from a character pointer in memory using the namelength

Here is the code:

errorLog.OutputSuccess("Filename reference: %c", *t_current_node->filename);

It of course only outputs the first character. If I add something like ->filename[nameLen] where nameLen is a valid integer of say 10 it says:

operand of * must be a pointer.

Thanks!

If the string is terminated with \0, you could use %s instead:

errorLog.OutputSuccess("Filename reference: %s", t_current_node->filename);

You also will need to pass the memory address of filename, so lose the *symbol.

Use %s, and remove the *

 errorLog.OutputSuccess("Filename reference: %s", t_current_node->filename);

• %c prints a single character.
• %s prints a string: all characters up to the terminating \0.
• %.10s prints the first 10 characters of a string (or less, if the string is shorter)
• %.*s takes two arguments, an integer indicating the length to print, and a string pointer.

Example for the last case:

printf("Filename reference: %.*s", nameLen, t_current_node->filename);
