C语言程序设计：输出结果题

1.输出:9 6

#include
int main()
{ 
 int x=1,y=2;
 for( ; x<10 ; x++)
 { 
 x+= 2;
 if ( x>7 ) break;
 if ( x==6 ) continue;
 y *= x;
 } 
 printf("%d %d\n",x,y);
 return 0;
}

2.输出2 6 42 3

#include 
int Square(int i)
{ 
 return i * i;
} 
int main( ) 
{ 
 int i = 0;
 i = Square(i);
 for( ; i<3; i++)
 { 
 static int i = 1;
 i += Square(i);
 printf("%d ", i);
 } 
 printf("%d\n", i);
 return 0;
}
  

3.输出 1 1

#include 
void swap(int *a, int b)
{ 
int m, *n;
n=&m;
*n=*a;
*a=b;
b=*n;
}
int main()
{
int x=8,y=1;
swap(&x,y);
printf("%d %d\n",x,y);
return 0;
}

4.11 22 33 0

#include
struct node
{
int data;
struct node *next;
};
int main()
{
struct node array[4]={{11},{22},{33}}, *p;
for( p=array ; p<array+3 ; p++ )
p->next = p+1;
p->next = 0;
p=array;
while ( p != '\0' )
{
printf("%d ",p->data);
p=p->next;
}
printf("\n");
return 0;
}

5.输出：20101622

#include 
void fun(char str[ ])
{ 
 int i,j;
 for (i=0,j=0;str[i];i++)
 if ( str[i]>='0'&&str[i]<='9') str[j++]= str[i];
 str[j]='\0';
} 
int main()
{ 
char str[100]="By the end of February of 2010, the total number of the teaching staff in 
NUPT has reached 1622.";
 fun(str);
 printf("%s\n",str);
 return 0;
}

6.输出11 13 17 19

#include
#include  
#include  
int main( )
{ int i,j,k;
 for (i=11;i<20;i=i+2)
{ 
k=(int)sqrt(i);
for (j=2;j<=k;j++) 
if (!(i%j)) break; 
 if (j>k) printf("%d,",i);
} 
return 0; 
}

sqrt()函数的返回值是 double型。

7.输出3，4，1，3，6，2，

#include 
int x; 
void f1( );
void f2(int);
int main( )
{ 
int i;
for (i=1;i<=2;i++)
{ x++;
 f1( ); 
 f2(x);
 printf("%d,",x);
}
return 0;
}
void f1( )
{ 
 int x=3;
printf("%d,",x++);
}
void f2(int y)
{ static int x=3;
printf("%d,",y+x);
 x++ ; y++ ;
}

8.输出:max=12,min=72

#include
gcd(int p,int q) 
{ 
if(p==q) return p;
else if(p>q )return gcd(p-q,q); 
else return gcd(p,q-p) ;
} 
int main()
{ 

int m=24,n=36,min,max;
max=gcd(m,n);
min=m*n/max;
printf("max=%d,min=%d\n",max,min); 
return 0;
}

9.输出3

#include 
int Cube(int i)
{
return i * i*i; }
int main( ) {
int i = 0;
i =Cube(i);
 for( ; i<3; i++)
{
static int i = 1;
 i +=Cube(i);
 }
printf("%d\n", i);
return 0;
}

10输出：edgrey

#include
#include
int main( )
{ 
char *p;
 char color1[10]= "red",color2[10]= "grey";
 p=color1; 
 p++;
 strcat(p,color2);
 printf("%s\n",p);
 return 0; 
}

11.输出：3，wang，2.67

#include
#include
struct st
{ int x;
 char str[10];
 float y;
}; 
void func(struct st *b)
{ 
 b->x=3;
 strcpy( b->str, "wang");
 b->y /= b->x;
} 
int main( )
{ 
 struct st a = { 10 , "x" , 8.0 } , *p = &a;
 func( p );
 printf( "%d , %s , %5.2f\n" , a.x , a.str , a.y);
 return 0;
}
