1、.1、输入3个数，求最大数。#includeusingnamespacestd;intmain(){inta,b,c,max;cout<<"请输入三个数字："<>a>>b>>c;max=(a>b)?a:b;if(c>max)max=c;cout<<"最大值："<usingnamespacestd;intmain(){inta;for(a=1;a<1000;a++){if(a%3==2&&a%5==3&

2、&a%7==2){cout<usingnamespacestd;intmain(){ints=0;inta=1;do{..s=s+a;a=a++;}while(a<101);cout<usingnamespacestd;intmain(){inta,s=0,s1=0,s2=0;for(a=1;a<101;a++,a++){s1+=a;}for(a=-2;a>-101;a=a-2){s2=s

3、2+a;}s=s1+s2;cout<usingnamespacestd;voidmain(){floata,m;floats=0;for(a=1;a<101;a++){m=1/a;s=s+m;}cout<<"s="<usingnamespacestd;intfac(intn){if(n==0)return1;elsereturnfac(n-1)*n;}intmain(){whi

4、le(1){intx,y,n;cout<<"输入一个整数：";cin>>x;fac(x);cout<usingnamespacestd;intmain(){ints=0;intt=1;intn;for(n=1;n<11;n++){t=t*n;s=s+t;}cout<<"1!+2!+3!+...+10!="<u

5、singnamespacestd;voidmain(){doubles=0;doublet=1;doublen=1;do{t=t*n;s=s+1/t;n++;}while(t<1e5);cout<<"1/1!+1/2!+1/3!+...+1/n!="<usingnamespacestd;voidmain(){doublesum=0.0;//结果doublenow=1.0;//现在的1／n！doublecnt=2.0;//现在的nwhile(now>=1e-5){sum+=now;now/=cnt;cnt+=1.0;}cout<

6、usingnamespacestd;intpow(intx,intn);intf1(intn);..intmain(intargc,char*argv[]){intx,n;doubleex=1;cin>>x;cin>>n;for(inti=1;i<=n;i++)ex+=pow(x,i)/(f1(i)*1.0);cout<

7、++)s*=i;returns;}intpow(intx,intn){ints=1;for(inti=1;i<=n;i++)s*=x;returns;}10、假定f1=1,f2=1;fn=fn-1+fn-2。输出前50项的值，且要求每行输出5个值#include#includeusingnamespacestd;intf(intn){intsum;if(n<=
