类型转换问题？

[zhaoxyu]

vc中除了强制类型转换外，还有那些方法？

如何将 long形数据转换成char* ？
如： long x＝11；
char* y；
y＝ ？？？x；

[zzzai]

用api ltoa

[Stephen_Ma]

long x=11;
char* y;

y=new char[length];
sprintf(y, "%ld", x);

类型转换只是为了编译通过,对内容不起作用.所以,类型转换,就是强制转换,没有其它的了.

Example

/* ITOA.C: This program converts integers of various
* sizes to strings in various radixes.
*/

#include <stdlib.h>
#include <stdio.h>

void main( void )
{
char buffer[20];
int i = 3445;
long l = -344115L;
unsigned long ul = 1234567890UL;

_itoa( i, buffer, 10 );
printf( "String of integer %d (radix 10): %s\n", i, buffer );
_itoa( i, buffer, 16 );
printf( "String of integer %d (radix 16): 0x%s\n", i, buffer );
_itoa( i, buffer, 2 );
printf( "String of integer %d (radix 2): %s\n", i, buffer );

_ltoa( l, buffer, 16 );
printf( "String of long int %ld (radix 16): 0x%s\n", l,
buffer );

_ultoa( ul, buffer, 16 );
printf( "String of unsigned long %lu (radix 16): 0x%s\n", ul,
buffer );
}


Output

String of integer 3445 (radix 10): 3445
String of integer 3445 (radix 16): 0xd75
String of integer 3445 (radix 2): 110101110101
String of long int -344115 (radix 16): 0xfffabfcd
String of unsigned long 1234567890 (radix 16): 0x499602d2
