C语言求x的y次方 fun函数实现x的y次方的计算 main函数中调用fun函数

void main(){//定义fun函数double fun(int x, int y);int x, y;double z;printf("请分别输入x,y的值：");scanf("%d %d",&x,&y);z = fun(x,y); //调用函数printf("%d的%d次方 = %lf\n",x,y,z);}double fun(int x, int y){double pow(double x, double y);double m = 0;m = pow(x,y); //求次方函数return m;}

运行结果如下：
