1、 . . . 1.5#include void main printf; printf; printf; 1.6#include void main float max; float a,b,c; printf; scanf; printfmax=%f,max; float max float m,n; m=xy? x: y; n=mz? m: z; return; 3.6 #include void main char c1=a,c2=b,c3=c,c4=101,c5=116; printf; printf; 3.9.1 #include void main double x=2.5,y=4
2、.7,z;int a=7; z=x+a%3*%2/4;printf; 3.9.2#include void main int a=2,b=3; float x=3.5,y=2.5,z; z=/2+x%y; printf; 4.5#include void main int a=5,b=7; double x=67.8564,y=-789.124; char c=A; long n=1234567; unsigned u=65535; printf; printf; printf; printf; printf; printf; printf; printf; printf; printf; 4
3、.6#include void main int a,b;float x,y;char c1,c2; scanf; scanf; scanf;4.7#includevoid main int a,b;float x,y,z;char c1,c2; scanf; scanf; scanf; 4.8#include #define pi 3.14void main float r,h,l,s1,s2,v1,v2; printf; scanf; l=2*pi*r; s1=pi*r*r; s2=4*s1; v1=4/3*pi*r*r*r; v2=s1*h; printf;printf;printf;p
4、rintf;printf;5.5 #include void main float x,y; printf; scanf; ifx y=x; else if=1&x y=2*x-1; else y=3*x-11; printf; printf; 5.6 #include void main float b; int a; printf; scanf; while b100 printf; scanf; a= int; ifa a=5; switchcase 10: case 9: printf;break; case 8: printf;break; case 7: printf;break;
5、 case 6: printf;break; case 5: printf;break; #include #include void main int x,y,m,n,i=1,j=0; printf; scanf; whilex=100000 printf; scanf; forn=0;n y=intx/pow; if0&y m=n+1;printf; printf; do printf %d,intx/pow%10; i+; while=0; printf; doprintf %d,intx/pow%10;j+; whilej-m;printf; 6.1输入两个正整数m和n,求其最大公约数
6、和最小公倍数。#include void main int m,n,i,j; printf; scanf; fori=1;i if j=i; printf; for if break;printf;printf; 6.2 题目：输入一行字符,分别统计出其中英文字母、空格、数字和其他字符的个数。#include void main int i=0,j=0,k=0,x=0; char c; printf; whilec=getchar!=n if=A&c=a&c i+; else if j+; else if=0&c k+; else x+; printf; printf; 6.3求Sn=a+aa+aaa+aaa之值,其中a是一个数字。例如：222222222222222此时n5,n由键盘输入。#include#include void main int i,n; int sum=0,s=0; printf; scanf; whilen printf; scanf; fori=0;i s+=pow; sum+=2*s; printf; 6.8 题
