1、1比较大小两个数//谭浩强书176主函数里的调用max函数有问题并且运行窗口一闪而过(1)#include#includeintmain(){floatmax(floatx,floaty);floata,b,c;printf("pleaseinputtwonumbers");scanf("%f,%f",&a,&b);c=max(a,b);//sleep(10);printf("thelagestnumberis:");return0;}floatmax(floatx,floaty){f

2、loatz;if(x>y)z=x;elsez=y;returnz;}(2)正确的解答方式，运行窗口最后可以停住#include#includefloatmax(floatx,floaty);intmain(){floata,b,c;printf("pleaseinputtwonumbers");scanf("%f,%f",&a,&b);c=max(a,b);//sleep(10);printf("thelagestnumberis:");while(1);return0;}floatm

3、ax(floatx,floaty){floatz;if(x>y)z=x;elsez=y;returnz;}2//水仙花数#includeintmain(){intnum,a,b,c;while(scanf("%d",&num)){if(num!=0){a=num%10;num/=10;b=num%10;c=num/10;if(a*a*a+b*b*b+c*c*c==num){printf("Yes");}elseprintf("No");}elsebreak;}return0;}3//输出小于某个数的

4、奇数和偶数（1）#includeintmain(){intn;scanf("%d",&n);inta;while(n--){scanf("%d",&a);for(inti=1;i<=a;i+=2)printf("%d",i);puts("");for(inti=2;i<=a;i+=2)printf("%d",i);puts("");}}（2）#includeintmain(){inta;while(a%2!=1){while(1){scanf("%d",&a);for(inti=1;i<=

5、a;i+=2)printf("%d",i);puts("");for(inti=2;i<=a;i+=2)printf("%d",i);puts("");}}}(3)//main函ˉ数簓里?：阰while语?句?应畖该?包悒?括ぁf和ífou语?句?#includeinta;intmain(){while(1){scanf("%d",&a);if(a%2!=1){for(inti=1;i<=a;i+=2)printf("%d",i);puts("");for(inti=2;i<=a;i+=2)printf(

6、"%d",i);puts("");}}}4比较五个数的大小并输出最大和最小值#includeusingnamespacestd;intmain(){inta,b,c,d,e,f,g;cin>>a>>b>>c>>d>>e;if(ac){f=c;}if(f>d){f=d;}if(f>e){f=e;}if(g

7、ncludeints[5];intt;inti;intmain(){for(i=0;i<5;i++)scanf("%d",&s[i]);for(intm=1;m<5;m++){for(intn=0;n<5-m;n++){if(s[n]>s[n+1]){t=s[n+1];s[n+1]=s[n];s[n]=t;}}}printf("%d%d",s[0],s[4]);while(1);return0;}5//输入成绩，系统分配等级，本例题中N代表总人数#includeintmain(){in

8、tn,score;scanf("%d",&n);while(n--){scanf("%d",&score);switch(score/10){case10:printf("A");break;case9:printf("A");break;case8:printf("B");b
