itoa

[vc_boy]

用_ltoa()

[playpcgame]

itoa,下面是例子
#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

Like printf() in c,You can use CString.Format(_T("%d"),i);

[maptrix]

还是用sprintf(buf,"%d %ld %f %lf",...);将数字转换字符串。

[quace]

Like printf() in c,You can use CString.Format(_T("%d",i);

[iforever]

_itoa

还是要看你用在哪儿

如CString.Format

等等

[sayu]

用itoa（#include "stdlib.h"）和CString::Format(...)分别实现DOS和WINDOWS下的数字/字符转换。
