1、实验五循环控制------实验报告(1)源程序:#includevoidmain(){intp,r,n,m,temp;printf("请输入两个正整数:");scanf("%d,%d,",&n,&m);if(n

2、:18.51-Win32Debug--------------------Compiling...18.51.c18.51.obj-0error(s),0warning(s)运行结果:(2)源程序:#includevoidmain(){charc;intletters=0,space=0,digit=0,other=0;printf("请输入一行字符：");while((c=getchar())!=''){if(c>='a'&&c<='z'

3、

4、c>='A'&&c<='Z')letters

5、++;elseif(c=='')space++;elseif(c>='0'&&c<='9')digit++;elseother++;}printf("字母数：%d空格数：%d数字数:%d其他字符数:%d",letters,space,digit,other);}调试结果:--------------------Configuration:18.52-Win32Debug--------------------Compiling...18.52.c18.52.obj-0error(s),0warni

6、ng(s)运行结果:(3)源程序:#include#includevoidmain(){floatx1,x0,f,f1;x1=1.5;do{x0=x1;f=((2*x0-4)*x0+3)*x0-6;f1=(6*x0-8)*x0+3;x1=x0-f/f1;}while(fabs(x1-x0)>=1e-5);printf("Therootofequationis%5.2f",x1);}调试结果:--------------------Configuration:18.53-Win

7、32Debug--------------------Compiling...18.53.c18.53.obj-0error(s),0warning(s)运行结果:分析:x1赋值的改变不影响最后所求的根的值,只是加大了运算次数.(4)源程序:#includevoidmain(){intday,x1,x2;day=9;x2=1;while(day>0){x1=(x2+1)*2;x2=x1;day--;}printf("total=%d",x1);}调试结果:------------------

8、--Configuration:18.54-Win32Debug--------------------Compiling...18.54.c18.54.obj-0error(s),0warning(s)运行结果:修改后:#includevoidmain(){intday,x1,x2;day=9;x2=1;while(day>0){x1=(x2+2)*2;x2=x1;day--;}printf("total=%d",x1);}--------------------Configuration

9、:18.54-Win32Debug--------------------Linking...18.54.exe-0error(s),0warning(s)
