C语言程序计算ax^2 bx c-搜答案-搜狗做题网

#include"stdio.h"voidfun(intn,intk){intj;doublesum=0;for(j=1;j

应该这样写：#include#includevoidmain(){inti,n,sum;sum=0;i=2;for(n=1;n

#includeintmain(){inti;doublesum=0.0;doublejiecheng(doublenumber);for(i=1.0;i

没得错误,main函数前面加void就好了

#includeintmain(){inti,j,sum,result=0;for(i=1;i

intfun(intn){//在该函数体中求1～n的累加值//用return语句返回累加值intsum=0;inti;for(i=1;i

#includemain(){doublex,y;scanf("%lf",&x);if(x

这个东西关键是递归算法的确定,需要一点数学知识.#include//递归计算函数intcalc(intx){if(xif(x==1){return1;}elseif(x==2){return3;}el

1+2+3+...100inti,s;for(i=1;i

#include#includeintmain(){intsum=0;intindex=0;for(index=1;index

#include#includevoidmain(){doublecoe[20],x,sum=0;inti,n;printf("请输入总项数:");scanf("%d",&n);printf("请按指

usingSystem;usingSystem.Collections.Generic;usingSystem.Text;usingSystem.Collections;namespacecacFC{

#include"stdio.h"voidmain(){inta[100],i;intcnt=0;for(i=0;i=-26&&a[i]

这个答案一眼就可以看出是-50,(1-2)+(3-4)+……(99-100)这样就是50个-1,非要用一个个计算,见下面代码：#include<stdio.h>main(){int&nbs

#include <stdio.h>int main(){ float x, tax = 0;

#include#include

你先把公式告诉我,我帮你写

运用了加法交换定律乘法交换律乘法分配律

#includevoidmain(){intn=1,N,i;scanf("%d",&N);if(N20)printf("shuruwuxiao!\n");else{for(i=1;i

#includeintmain(){inti,s=0;for(i=1;i
