#include "stdio.h"
#include "math.h"
void main()
{    double pow(x,y);
    double x,y;
    printf("请输入X,Y的值：");
    scanf("%f,%f",&x,&y);
    printf("%f",pow(x,y));
}
为什么无论输入 的x,y是何值，输出都为1.000000

#include "stdio.h"
#include "math.h"
void main()
{    double pow(x,y);
    double x,y;
    printf("请输入X,Y的值：");
    scanf("%lf,%lf",&x,&y);
    printf("%lf",pow(x,y));
}

work nine.exe - 4 error(s), 0 warning(s)

我运行楼上的,出现错误,第1和2条,我还理解.第3和4是什么意思啊?

#include <stdio.h>
#include <math.h>

int main()
{
    double x, y;

    scanf("%lf%lf", &x, &y);
    printf("%g\n", pow(x, y));
    return 0;
}

这样试试。

搞定了 谢谢
