strcat syntax with int and char

[2005]

Hi

I have

char String[] = "Time";
char temp[];
int slot;

slot = 1;

What I need is:= String[] = "Time1"

temp = (char)slot
strcat(String, temp);

Something is a miss - could someone fix it for me pls.

Java programmer?

something like the following:

const char *String = "Time";
char *temp = (char*)malloc( strlen( String ) + 20 +1 ); /*assume int
can be printed in 20 chars */
int slot = 1;

sprintf( temp, "%s%d", String, slot );
/* code using temp */
free( temp);

/* This is off the top of my head - I haven't compiled this - brave in
this group */

You want something like this:

char String[LONG_ENOUGH];
sprintf(String, "Time%i", slot)

or just
char String[] = "TimeX"; /* the X is important */
String[5] = '0' + (char)slot;

but it works only for 0 <= slot <= 9.

That should be

>
const char *String = "Time";
char *temp = (char*)malloc( strlen( String ) + 20 +1 ); /*assume int
can be printed in 20 chars */
int slot = 1;

if ( temp != NULL ) /*need to test that malloc succeeded*/
{

>
sprintf( temp, "%s%d", String, slot );
/* code using temp */
free( temp);

}

I think you mean:
String[4] = '0' + slot;

Arrays are indexed from 0 in C, and also it does not make any
difference if you cast 'slot'.
