Hello
can someone help me to complete a program that allows the user to input names
and for the output it should prints the names in alphabetical order.

starting would be something like that.

#include <stdio.h> 

struct sort_names 
{ 
char node_str [80]; 
struct sort_names *next; 

};

the code isn't complete . I tried modifying a little bit but it

Untitled 40.c:7:11: fatal error: 'conio.h' file not found
        #include <conio.h>
                 ^
1 error generated.

didn't wok.

is there code that didn't use <conio.h> and use <stdlib.h> or <string.h> which I'm familiar with.

I looked at that code and didn't see where you couldn't comment out conio.h.

Remember you didn't specify what compiler or such. So any code will do. I took it to an online .c compiler and changed it a bit.

Runs now.

I'm sure you can fix it up from here at http://www.onlinecompiler.net/ccplusplus
