#include<stdio.h>

     {
         
         xpow = power(x,exp);                         //这里power(x,exp)   也就是指的 x乘以x exp次  调用了开头那个power算法，给里面的n，p赋值 了
         printf("%.3g to the power %d is %.5g\n",x,exp,xpow);   // 这里为何出现的%.3g啊  而不是%lf  
         printf("Enter next pair of numbers or q to quit .\n");
         
     }

        double power(double n,int p)      //这行是什么 也不明白
        {
            double pow =1 ;
            int i;
            
            for(i = 1; i<=p; i++)     //这里就是 没有键入字符q 就不结束循环把
            pow *= n;                  //pow = pow*n

自学不易  麻烦帮忙帮忙

整个代码理解的不连贯 半懂不懂
