You can:
a) use a string return type
b) use a string pointer argument
c) use a string reference argument if the string already exists in the calling function.

#include<iostream.h>
#include<conio.h>

You are not returning a string.

You are returning a pointer to a char.

Where is your string???

You cant return a character array from a function as the character array will be gone as the function returns.
Instead you shuld declare a pointer,allocate memory for it,get the inpyt and then return it.
You have written most of it and i am adding the missing links

char *a()
{
char *name=new char[100];//I am keeping it as 100.Plese chage it as per ur req.
cin>>name;
return(name);
}
 

Thanks
