String

Question

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void a(char**strref){
++strref;
}
int main() {
char *s="hour";
a(&s);
puts(s);
return 0;
}
I think the result of the code is “our”,but not. Who can tell me why? 😹

Answer 1

You need to change ++strref; to ++*strref;
This is because without the * then it’s just changing the value of strref inside the a function, not inside the main function.

P.S. Next time, please put the programming language as a tag!

Answer 2

No worries!
