c语言编程求改错.按下面要求编写程序:(1)定义函数cal_power(x,n)计算x的n次幂(即xn),函数返回值类型是double.(2)定义函数mai
1、值传递,计算x的n次幂 #include <stdio.h>doublepower(doublex,intn) {inti;doubletmp =1.0;for(i =1; i <= n; i++) { tmp*=x; }returntmp; }intmain(void) {doublea;intb; puts("please input the value of a and b."); printf("a ="); scanf("%lf", &a); printf("b =");...
//（1）定义函数(x,n),计算x的n次幂#include "stdio.h"double f(double x,int n){ double s=1.0;int i;for(i=1;i<=n;i++){ s=s*x;} return s;} void main(){ double x;int n;printf("请输入x:");scanf("%lf",&x);printf("请输入n:");scanf("%d",&n);printf("...
include <stdio.h>int main(){float a,s=1;int n; printf("输入一个正实数\n");scanf("%f",&a);printf("输入一个正整数\n");scanf("%d",&n);while(n>0){s*=a;n--;}printf("%f的%d次幂是%f\n",a,n,s);return 0;} ...
include <stdio.h>float xn(int x,int n){ int i; float s=1; for(i=1;i<=n;i++) { s=s*x; } return s;}int main(){ int x,n; float result; printf("please input x:"); scanf("%d",&x); printf("please input n:"); scanf...
include<stdio.h> int Xn(int x,int n)//x的n次幂(n>=0){ if(n=0)return 1;else if(n=1) return x;else return(Xn(x,n-1));} void main(){ int a,b,xn;scanf("%d %d",&a,&b);xn=Xn(a,b);//a的b次幂 printf("The result is:%d",xn);} ...
double cal_power(double x,int n){double y=1; for(;n;n--) y*=x; return y;}
int fun(int a){ if(a==1)return a;return fun(a-1)*a;}
double power(double x,int n){ //int a;//for(a=1;a<=n;a++) 用递归就不需要循环 if(n==0) return 1;//0次方 else return x*power(x,n-1);//递归为x*x的n-1次方 // printf("%f",power(x,n));不用输出了，否则又调用一次power } /* 如果要用循环，可以用下面这段...
函数fun的功能是计算x^n。主函数中已经正确定义m、a、b变量并赋值,并调用fun函数计算:m=a^4+b^4-(a+b)^3。(说明:x^n即x的n次幂)#inclu
