I am a beginner of c language, and trying to use trim function in a main. But I don't know what going on with my program? So please correct me. Thank you so much

The program is as follow:

#include<stdio.h>
#include<string.h>

int trim(char s[])
{
int n;

for (n = strlen(s)-1; n >= 0; n--){
if (s[n] != ' ' && s[n] != '\t' && s[n] != '\n')
break;}
s[n+1] = '\0';
return 0;
}

main()
{
char s[30] = "fly egle\t and\n fly again";
trim(s);
printf("%s\n",s);
}
