double x = 2.0, y = 3.0, z;
z = power(x, y);
printf("%.1f to the power of %.1f\n", x, y, z);

double z=1;

}

}
printf("%.1f to the power of %.1f is %.1f\n", x, y, z);
z参数输出还少一个是少一个%f。
Exited with error status 28 的报错的话是因为缺少主函数。
将void main 改为 int即可。
没有什么大问题呀!运行起来有警告而已。
#include <stdio.h>
#include <stdlib.h>
double power(double x, double y);
int main()
{
double x = 2.0, y = 3.0, z;
z = power(x, y);
printf("%.1f to the power of %.1f is %.1f\n", x, y, z);
return 0;
}
double power(double x, double y)
{
double z=1;
while (y)
{
z *= x;
--y;
}
return z;
}
刚才查了一下资料,c标准里规定main返回值必须为int,虽然能运行,但是会有警告。
