简单C语言程序的例子

1、例子：誓#in elude <stdio.h>ma in ()tips();/*caller*/printf(“ n Success is about banging on after others have let go”);tips()/*caller*/printf (“n When you reach the end of the rope tie a knot & hang on” ,)0;上述程序的输出结果如下：When you reach the end of the ropt tie a knot & hang on.#in clude <st

2、dio.h>ma in ()int a,fact;printf(“nEnter any number ” );scanf( “ %d，&a);fact=rec(a);printf( “ Factorial value is%d ” ,fact);Success is about hanging on after others have let go.其显示的结果为：Factorial value is 2.-比较两个数较大的那个:#in clude <stdio.h>main ()int a,b,max;scanf (“ d%”，&a,&b);if (

3、a>b)max=a;else max=b;printf (“ %d ,max);- 输出a+b的值：#in elude <stdio.h>void mai n()int a,b, x;scanf (“ d%”，&a,&b);x=a+b;printf (“ d ,x);- 输出a,b中最大的一位数:#in clude <stdio.h> int max(i nt x,i nt y)int乙if (x>y) z=x; else z=y;return(z);void mai n()int a,b,c;scanf (“ d%”，&a,&

4、;b);c=max(a,b);printf (“ dn" ,c);-输出 Hello:#in clude <stdio.h>int mai n()printf (“ Hello! ” );return 0;- 求1100的和:#in clude <stdio.h>int mai n()int s,n;s=0, n=1;A: s=s+n;n=n+1;if (n <=100)goto A;printf (“ d' ,s);-请输入一个三位数，将其各位逆序输出：（如153，输出351）#in clude <stdio.h>void mai

5、n()int x,y,a,b,c;printf （"请输入一个三位数的数："）;scan f("%d", &x);a=x/100;b=x%100/10;c=x%10;y=c*100+b*10+a;printf ("n%d",y); |#in clude <stdio.h>void mai n()int x,a,b,c,d;printf （"请输入一个三位数的数："）;scan f("%d", &x);a=x/100; b=x%100/10;c=x%10; d=c*10

6、0+b*10+a; printf ("n%dn",d);买鸡:#in elude <stdio.h>void mai n()int x,y,z;if(x>=0&& x<=19,y>=0&& y<=33,z>=0&&z<=100) while (x=19) |x=0;5*x+3*y+z/3=100&& x+y+z=100; x=x+1;|printf("%d%d%d",x,y,z);0y=(100-5*x-z/3)/3&& y=1

7、00-x-z;z=(100-5*x-3*y)*3&&z=100-x-y;#in elude <stdio.h>void mai n()0int x=0,y,z;while (x<=19)5*x+3*y+z/3=100&& x+y+z=100; x=x+1;prin tf(”d%d%d”,x,y,z);#in elude <stdio.h> void mai n()int x=0,y=0,z=0; while (x<=19)while (y<=33)'while (z<=100)计算 x=20+3(x-1):

8、#in elude <stdio.h>void mai n()int age(i nt x)int i,j;scanf( “ %d，&i); j=age(i);printf(“ age=%dn”，j);int age(i nt x)int 乙if(x=1) z=20;else z=age(x-1)+3;return(z);J编写程序求圆柱体的表面积和体积:#i nclude <stdio.h>#defi ne PI 3.14/*void mai n() float r,h,s,v;printf(定义PI为符号常量，值为3.14*/“请输入半径r和高h的值：n ”

9、）；输入半径r和高h*/ 计算圆柱体表面积*/ 计算圆柱体体积*/scanf( “ f%” ，&r,&h);s=2*PI*r*h;v=PI*r*r*h;printf( “ s=%f,v=%fn/*/*-自增，自减运算符的使用:/*,s,v);#in elude <stdio.h> void mai n()int i=5,j=5;int x,y;y=+j;printf(“ dt%dn ” ,-x+,-(+y);printf(“ %dt%dt%dt%dn ” ,i,j,x,y);-自增、自减运算符的基本运算：#in elude <stdio.h>void m

10、ai n()int k=4;int x,y,z;x=18-k+;printf(“ x=%d' ,x);printf(“ k=%dn” ,k);y=+k+6;printf(“ y=%d' ,y);printf(“ k=%dn” ,k); Jz=+k+k+;printf( “ z=%dn”，z);结果：x=14,k=5;y=12,k=6;z=14.- 输出单个字符:#in elude <stdio.h>void main()char a,b;a=' o'b=' k'putehar(a);putehar(b);putehar( n '

11、;);-输入字符举例：#in elude <stdio.h>void mai n()char c;c=getchar(); /*从键盘读入一个字符 */putchar(c);/*显示输入的字符*/猜数游戏:#i nclude <stdio.h>#in clude <stdlib.h> #in clude <time.h>int mai n()if (i>=10)break;printf（”随机数是：%dn",x）;printf（”你已经猜 错了 10次，我赢了，哈哈！ n"）;prin tf（"请你再猜：&qu

12、ot;）;while(1);#in elude <stdio.h>void mai n()int a=2,*p=&a,*q=&a;Prin tf("%d,%dn",*p+,*(q+);P=&a;q=&Printf ("%d%dn",*p,(*q)+);Prin tf("%d%dn",*p,+(*q);结果为：2,22,24,4（从又向左算）Printf ("a=%d,b=%dn",*pa,*pb);C=a+b;Printf ("c=%dn",*pc); *pc=a+*pb;Printf ("c=%d从100到200之间有哪些数除 4多2,除7多3，除9多5?#in clude<stdio.h> int mai n()for(i nt i =
