Why this code has no output?

Question

char *str = "12345";
printf(" %s", *str);

Answer 1

*str means you are dereferencing a character, at the address pointed by pointer <str>. The problem here is you are using %s which is meant for string rather than character. Use %c instead of %s and you will get output.

Use %s if you want to print the string, but don't use dereference operator '*', -> printf(" %s", str);
