How do i convert char into a string (*char)

[Xerxes333]

How Should I do this properly?
int main ( )
{
char *string="empty";
char item='2';
//at this point i am trying to convert 'h'
//into "h" so that i can use atoi( )
string=item;
cout << string << endl;
return 0;
}
Any and all help is greatly appreciated

I know this is true of C and am almost certain it is true of C++: you can't modify the string literal pointed to by string in your example -- doing so causes undefined behavior.

In this case, just assign it to the proper element of string:

char string[20];
char item='2';

string[0]=item;
string[1]='\0' /* Add the terminating null */

Now string is &quot;2&quot;

Or, use sprintf... but Russ way is better (I think) this is more generic...

sprintf(string, &quot;%s&quot;, item);

oops, should be:

sprintf(string, &quot;%c&quot;, item);

item is a char, not a char *
