例子:

#include

main ()

{

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.

Success is about hanging on after others have let go.]

#include

main()

{

int a,fact;

printf(“\nEnter any number”);

scanf(“%d”,&a);

fact=rec(a);

printf(“Factorial value is%d”,fact);

}

rec(x);

int x;

{

int f;

if(x==1)

return(1);

else

f=x*rec(x-1);

return(f);

}

[其显示的结果为:Factorial value is 2.]

比较两个数较大的那个:

#include

main()

{

int a,b,max;

scanf (“%d%d”,&a,&b);

if (a>b)

max=a;

else max=b;

printf (“%d”,max);

}

输出a+b的值:

#include

void main()

{

int a,b,x;

scanf (“%d%d”,&a,&b);

x=a+b;

printf (“%d”,x);

}

输出a,b中最大的一位数:

#include

int max(int x,int y)

{

int z;

if (x>y) z=x;

else z=y;

return(z);

}

void main()

{

int a,b,c;

scanf (“%d%d”,&a,&b);

c=max(a,b);

printf (“%d\n”,c);

}

输出Hello:

#include

int main()

{

printf (“Hello!”);

return 0;

}

求1~100的和:

#include

int main()

{

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)

#include

void main()

{

int x,y,a,b,c;

printf ("请输入一个三位数的数:");

scanf("%d",&x);

a=x/100;

b=x%100/10;

c=x%10;

y=c*100+b*10+a;

printf ("\n%d",y);

}

#include

void main()

{

int x,a,b,c,d;

printf ("请输入一个三位数的数:");

scanf("%d",&x);

a=x/100;

b=x%100/10;

c=x%10;

d=c*100+b*10+a;

printf ("\n%d\n",d);

}

买鸡:

#include

void main()

{

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);

}

y==(100-5*x-z/3)/3&&y==100-x-z;

z==(100-5*x-3*y)*3&&z==100-x-y;

#include

void main()

{

int x=0,y,z;

while (x<=19)

{

5*x+3*y+z/3==100&&x+y+z==100;

x=x+1;

printf("%d%d%d",x,y,z);

}

}

#include

void main()

{

int x=0,y=0,z=0;

while (x<=19)

{

while (y<=33)

{

while (z<=100)

{
