sscanf分离double数

[underuwing]

我用sscanf分离int型数据，是正常的如下所示：

#include <stdio.h>
int main()
{
    char buf[]="22,115";
    int x;
    int y;
    sscanf(buf,"%d,%d",&x,&y);
    printf("x=%d\n",x);
    printf("y=%d\n",y);
    return 0;
}

但是分离double型数据时，为什么得到的是错误的数据呢？
如下：

#include <stdio.h>
int main()
{
    char buf[]="22.123,115.123";
    double x;
    double y;
    sscanf(buf,"%f,%f",&x,&y);
    printf("x=%f\n",x);
    printf("y=%f\n",y);
}

double对应scanf时用%lf
printf使用%f

楼主看看scanf格式控制符就知道了.
sscanf(buf,"%f,%f",&x,&y);
-->
sscanf(buf,"%lf,%lf",&x,&y);

#include <stdio.h>
int main()
{
    char buf[]="22.123,115.123";
    double x;
    double y;
    sscanf(buf,"%lf,%lf",&x,&y);
    printf("x=%lf\n",x);
    printf("y=%lf\n",y);
}

2楼正解，double对应的是%lf，float对应的才是%f

double对应的是%lf，float对应的才是%f

[cattycat]

%lf

[canshui]

double和long double型对应的是%lf
float对应的是%f
float 是4字节赋值
double 是8字节赋值
long double是不小于8个字节
