顺序结构第一题#includestdio.hvoid main(){printf( * \n);printf( * * * \n);printf( * * * * * \n);}顺序结构第三题#includestdio.hvoid main(){float h=3.0,r=1.5,c,s,s1,v,v1; //定义变量float pi=3.1415926; //c为圆周长，s为圆面积，s1为圆球表面积，v为圆球体积，v1为圆柱体printf(请输入高和半径:\n);scanf(%f%f,r,h);c=2.0*pi*r; //求解s=r*r*pi;s1=4.0*pi*r*r;v=(4.0/3.0)*pi*r*r*r;v1=pi*r*r*h;printf(c= %6.2f\n,c);printf(s= %6.2f\n,s);printf(s1= %6.2f\n,s1);printf(v= %6.2f\n,v);printf(v1= %6.2f\n,v1);printf(\n);}}顺序结构第二题#includestdio.hint main(){char c;c=getchar(); //从键盘上读入一个字母while(c!=\n){if(c=Ac=Z||c=ac=z) //判断是否为字母{if (c=xc=Z||c=Xc=Z)c=c-23; else c=c+3;}printf(%c,c);c=getchar();}printf(\n);return 0;}选择结构第一题（灵感来源于P100顶头）1.完整编码：#includestdio.hint main(){inta,b,c,max；scanf(%d %d %d,a,b,c);if(ab)if(ac)max=a;else max=c;if(bc)max=b;else max=c;printf(max=%d\n,max);return 0;}第二种way：/*------------------------------------------------[程序设计]--------------------------------------------------有3个整数a,b,c,由键盘输入，输出其中最大的数max。------------------------------------------------*/#includestdio.hvoid main(){ /**********Program**********/inta,b,c,max;scanf(%d %d %d,a,b,c);if(ab)if(ac) max=a;else max=c;else if(bc) max=b;else max=c;printf(max=%d\n,max); /********** End **********/}3测试数据及运行结果：2.流程图y输入整数a,b,c,maxab?N Nbc?ac?YYmax=aNmax=bmax=cYY输出max顺序结构第二题完整代码#includestdio.hvoid main(){ double len,wid,hei,weight,money; //定义变量：len为长度，wid为宽度，hei为高度，weight为重量，money为费用，i为计数,p为包裹inti;printf(请输入包裹的长len=:\n请输入包裹的宽度wid=:\n请输入包裹的高度hei=:\n请输入裹的重量weight=:\n请输入包裹的件数i=\n);//输入l,w,scanf(%lf %lf %lf %lf %d,len,wid,hei,weight,i);if(len1||wid1||hei1||weight30) //判断包裹是否合格printf(不予邮寄：\n);else{if(weight=10)money=1.00*weight+0.5*i; //如果合格在判断else if(weight10 weight=20) money=0.90*weight+0.5*i;else if(weight20 weight=30) money=0.80*weight+0.80*i;printf(money=%.2lf\n,money);}}Switch型#includestdio.hvoid main(){inti;d
