Længden op en var ?

her er en billig metode :-)

char array[25];
sprintf( array, "%d", i );
int cifre = strlen( array);

#include <string.h>

Jeg har smidt:

****************************************
#include "string.h"
#include "stdio.h"

int main()
{
int i = 1234;

char array[25];
sprintf(array, "%d", i );
int cifre = strlen( array);
return 0;
}
*********************************************
dette ind og får denne error:
*********************************************

hmm, virker fint i visual c++

prøv med itoa istedet


#include "string.h"
#include "stdio.h"
#include "iostream.h"
#include <stdlib.h>

int main()
{
int i = 1234;

char array[25];
_itoa( i, array, 10 );
sprintf(array, "%d", i );
int cifre = strlen( array);
cout << cifre << endl;
return 0;
}

ups

char array[25];
_itoa( i, array, 10 );
//sprintf(array, "%d", i );
int cifre = strlen( array);
