帮忙写个C++小程序，很简单

#include"stdio.h"
#include"math.h"
void main()
{
int a ,b,c;
printf("please input a ,b:\n");
scanf("%d,%d",&a,&b);
c=pow(a,b);
printf("a的b次方为:%d",c);
}

#include

int myPow(int a,int b)
{
int ret=1;
while(b--)ret*=a;
return ret;
}
int main()
{
int a,b;
scanf("%d%d",&a,&b);
printf("%d\n",myPow(a,b));
return 0;
}

#include
using namespace std;

int main()
{
int a,b;
cin>>a>>b;
int result=1;
for (int i=0;i {
result*=a;
}
cout<<"result is "< return 0;
}

#include
#include
using namespace std ;
int main()
{ double a , b ;
cin>>a>>b ;
cout<}

pow(a,b);
