1、东风一中智能机器人C语言程序上机试题 东风一中高中中生智能机器器人班C语言言上机试题1-2 求两两数之和。# incluude Void mmain( ) int aa ,b , sum ; a=6; bb=99; sum = a + b ;printf(“sum iis %d”, sum)；eg2-1. 用海龙公式式求三角形面面积（设输入入的三边长能能构成三角形形）#includde “math.h”main () floatt a,b,c,p, area;scanf (“%f,%ff,%f ” ,&aa,&b,&c) ; p= (a+bb+c) /2;area=sqqrt(p*(p-a)*
2、(p-bb)*(p-c) ;printf ( “a=%7.22f, b=%7.22f, c=%7.2f n” , a, b, c);printf (“area=%7.2ffn”,areaa);eg2-2输入入三个数，输输出其中的最最大者# incluude void maain() int a,b,c,mmax; Printf (“enterr a,b,&c:nn”);scanf(“%d,%dd,%d”, &a,&b,&c); max=a; if (maxxb) max=b;if (maxxbb) t=a;a=b;bb=t;if (acc) t=a;a=b;bb=t;if (bcc) tt=b
3、;b=c;c=tt;printf(“%5.2f, %5.2ff,%5.2ff ”, a,bb,c); 又解# incclude void maain() int mmax(innt x, int yy) ; int a,bb,c;printf (“inputt a,b: ”);scanf (“%d,%dd”, &a,&b); c=max(aa,b);printf(“max = %d n”,c”)int maax(intt x, iint y) int zz; if (xyy) z=xx;else z=y;return(z); void maain( )int a, b;prinntf(iinp
4、ut two nnumberrs: )；scanf(%d%dd,&a,&b);if(ab) priintf(max=%dn,a) ；elseprinttf(maax=%dn,b)； void maain()int aa,b;prrintf (pllease inputt A,B: );sscanf (%dd%d,&a,&b);if(aa!=b)iif(abb) priintf(ABnn);ellse iff (a= = b) printtf(A=Bn);elsee prinntf(AAb ? a ：b); 3-1 输入字字符的ASCCII码，若若为字母或数数字，须指出出。#includde v
5、oid main()chhar c;prinntf(iinput a chaaracteer: );c=ggetchaar();if(c=0&c=A&c=a&cc=z)prrintf(Thiss is aa smalll lettternn);eelseprinttf(Thhis iss an oother charaactern);if(c=0&c=A&c=aa&c1000 | sscore 0 ) prinntf(“n daata errror”);Scanf(“%f”, &sccore);（(int) (scorre/10）Case10: graade=A;breaak;Case9: g
6、radee=A;breaak;Case 8: gradde=B;breaak;Case 7: gradde=C;breaak;Case6: gradee=D;breaak;Case5:Case4:Case3:ccase2:case11:casee0: grrade=E; Printf(“成绩%5.11f, 等级级%cn” , sscore,gradee );例4-1 符号号常量的使用用 运行结果： China! Glmre! #definee priice 50#includde Void maain ( ) int nnum, ttotal; Num= 10; Totall=num * pr
7、iice; Printtf(“totall = %dd”, tottal)#includde#incllude voiid maiin()ffloat a,b,cc,s,arrea;sccanf(“%f,%ff,%f,&a,&b,&c);ss=1.0/2*(a+b+c);area=sqrt(s*(s-a)*(ss-b)*(s-c);prinntf(“a=%7.22f, bb=%7.22f, cc=%7.22f, ss=%7.22fn”,a,b,c,s);printtf(“area=%7.2ffn”,areaa);例1.3 求33个数中较大大者。#inncludee void main( ) i
8、ntt max(int xx,int y); / intt a, bb, c; scanff(d,dd,&a,&b); c=mmax(a,b); priintf(max=dn,c); int maax(intt x, iint y) int z; if (xy) z=xx; elsee z=y; retuurn (zz); 例6.1 求求1到100的和voidd mainn( ) iint i， sum=0; ffor (i=1; i=1000,i+) sum=sum+ii; priintf(%dnn，sum); 例6.2 求求1到100的和#incclude vvoid mmain() iint i，ssum=0; ii=1; whiile (ii=1000) suum=summ+i; i+; printtf(%dnn，sum); 例6.4 whhile和do-whhile循环环的比较 (1) #incluude
