pow(x,n);
pow(x,y);其作用是计算x的y次方。x、y及函数值都是double型 ，应用时需要加入头文件 math.h
例如：
#include<math.h>
#include<stdio.h>
int main()
{
doublex=2.0,y=3.0;
printf("%lf raised to %lf is %lf
",x,y,pow(x,y));
return0;
}
int x,n,ans=1,q=0;
scanf("%d%d",&x,&n);
for(q=0;q<n;q++) ans*=x;
while (q<n)
{
ans*=x;
q++;
}
do
{
ans*=x;
q++;
}while (q<n)
