1、第三章程序和流程控制I.输入两个整数，输出较大者。#includevoidmain(){inta.b;intmax=0;printf(MPleaseinputtwonumbers:11);scanf(”％d%d",&a,&b);if(a<=b)max=b;elsemax=a;printf(MThelargernumberis%dn,max);}2.冇3个整数a,b,c,由键盘输入，输出英中最大的数。#includevoidmain(){inta,b,c,max;printf(HPlease

2、inputthreenumbers:0);scanf(”％d%d%d“,&a,&b,&c);if(a>b){if(a>c)max=a;elsemax=c;}else{if(b>c)max=b;elsemax=c;}printf(MThelargestnumberis%d,temp);}3.从1累加到100,用while语句。#includc#defineN100voidmain()inti=hsum=O;while(i<=N){sum+=i;i++；}printf("sum:%d'sum);}2.已

3、知al=10,a2=_3,an=3an-l+an-2,求{a}的前十项。#include#dcfincN10voidmain(){inta[20]={10,-3);inti=0,m=();for(i=2;ivo

4、idmain(){inta,temp;printf(HPleaseinputanumbers:H);scanf(”％d”,&a);temp=a%2;if(tcmp==0)printf(HThenumber%disaneven!H5a);elseprintf(nThenumber%disanoddnumber!,a);}4.已知al=8,an=an・l+bn,bl=1,bn=bn・l+3,求{a}前10项之和。#include#dcfincN10voidmain(){inta[N]={8},b[N]

5、={1},i,sum二0;for(i=l;ivoidmain(){floatx,y;printf("Pleaseinputafloatnumberx=:M);scanf("%f&x);printf(”x=%f',x);if(

6、x<1)y二x;elseif(x>=10)y=3*x-l1;elsey=2*x-l;printf("Thevalueofyis:%.3f”,y);}3.给一个不多于5位的的正整数，要求：求出它是儿位数，分别打印出每一位数字，最后按照逆序打印各位数字,例如原数为321,应输岀为123。#include#dcfincN99999#defineM5voidmain()inti,j,k,m,b[M];longinta,temp;printf(MPleaseinputanumber:H);scanf("%ld",

7、&a);if(a<()

8、

9、a>N)printf("Errorininputdata!!!");else{temp=a;fbr(i=0;temp!=0;i++){temp=temp/10;}m=i;printf(MThenumbera=%ldhave%dsinglenumbersiV；a，m);temp=a;for(j=0;j

10、[k]);}printf(““)；printf(neveryletteris:”)；for(j=m-l;j>=();j—)printf(”％dt”,b[j]);printfC*^");printf("Theinvertednumbersare:");f
