2进制的long整型以CString表示，怎么转换成long型

[lilizz]

比如：CString str = "00001111000000001111111100000000";

str表示的long型整数应等于251723520

用CString的sprintf方法可以转换，不知怎么转。

请dx告知。

char *end;
CString str = "00001111000000001111111100000000";
long a = strtol(str,&end,2);//现在 a = 251723520 了

atol

CStirng strSource = "00000000001111111111111100011111";
char* result ;
long ret = atol(strSource,result,2)
就OK了。其实和StdAfx的做法是一样的！
呵呵……

我怎么一直没有看到过 atol 带三个参数的啊.
你记错了。

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

void main( void )
{
char *string, *stopstring;
double x;
long l;
int base;
unsigned long ul;
string = "3.1415926This stopped it";
x = strtod( string, &stopstring );
printf( "string = %s\n", string );
printf(" strtod = %f\n", x );
printf(" Stopped scan at: %s\n\n", stopstring );
string = "-10110134932This stopped it";
l = strtol( string, &stopstring, 10 );
printf( "string = %s", string );
printf(" strtol = %ld", l );
printf(" Stopped scan at: %s", stopstring );
string = "10110134932";
printf( "string = %s\n", string );
/* Convert string using base 2, 4, and 8: */
for( base = 2; base <= 8; base *= 2 )
{
/* Convert the string: */
ul = strtoul( string, &stopstring, base );
printf( " strtol = %ld (base %d)\n", ul, base );
printf( " Stopped scan at: %s\n", stopstring );
}
}


Output

string = 3.1415926This stopped it
strtod = 3.141593
Stopped scan at: This stopped it

string = -10110134932This stopped it strtol = -2147483647 Stopped scan at: This stopped itstring = 10110134932
strtol = 45 (base 2)
Stopped scan at: 34932
strtol = 4423 (base 4)
Stopped scan at: 4932
strtol = 2134108 (base 8)
Stopped scan at: 932

TCHAR* szStop=NULL;

nVal=_tcstol(strString,&szStop,2);
