希望大家能在源程序上修改，以实现要求。谢谢！

[fly]谢谢[/fly]

scanf("%d %ld",&a,&b);
    m=a;

郁闷了,这是什么意思,转成字符串?只赋三位什么意思
求解幂函数??你在搞什么,是y=x^a还是什么,

#include<stdio.h>
#include<math.h>
int main()
{
int i,j,k,sum;
printf("请输入底数");
k=scanf("%d",&i);
printf("请输入幂级数");
scanf("%d",&j);
while(1)
{
sum=pow(i,j);
printf("%d的%d次幂是%d\n",i,j,sum);
printf("请输入底数");
k=scanf("%d",&i);
if(!k)
 break;
printf("请输入幂级数");
scanf("%d",&j);
}
getch();
return 0;
}

//输入字母时结束~输入回车不好控制 因为scanf()默认就是回车结束  比如你输入一个数字3回车之后 scanf当做执行结束符
