这个程序为啥运行不了，求学霸解答

Question

#include <stdio.h>
double power(double x, double y);
int main()
{
double a, b, c;
printf("请输入一个数及它的次方：\n");
scanf_s("%.1f,%.1f", &a, &b);

c=power(a, b);
printf("%.1f的%.1f次方是%.1f", a, b, c);
return 0;

}
double power(double x, double y)
{
double c=1.0;
while (y)
{
c *= x;
y--;
}return c;
}

Answer 1

尝试将%.1f改为%.1lf,double要使用lf进行输入与输出
