输入double x,y 计算并输出sin(x)、cos(x)、|x|、ex、xy的值。

我可以回答这个问题。sin(x)、cos(x)、|x|、ex、xy的值可以通过数学库函数来计算，具体实现方法如下：

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

int main()
{
double x, y;
scanf("%lf %lf", &x, &y);

double sin_x = sin(x);
double cos_x = cos(x);
double abs_x = fabs(x);
double exp_x = exp(x);
double xy = x * y;

printf("sin(x) = %lf\n", sin_x);
printf("cos(x) = %lf\n", cos_x);
printf("|x| = %lf\n", abs_x);
printf("e^x = %lf\n", exp_x);
printf("xy = %lf\n", xy);

return 0;
}
