int a=3,b=4,*q=&b; *q=a+b;a=5; q=(a
int a=3,b=4,*q=&b; *q=a+b;a=5; q=(a
int a=3,b=4,*q=&b; *q=a+b;a=5; q=(a
int a=3,b=4,*q=&b; //定义a,b两个整形变量并赋值.定义整形指针变量q,并将变量b的地址赋给q.& 就是取地址.
*q=a+b;//*q表示指针变量q指向的地址,将a+b的值赋给这个地址.就是b代表的地址.b=a+b=3+4=7
a=5;//给a赋值.a=5
q=(a<b)?&a:&b;//表达式1?表达式2:表达式3.如果表达式1是真值,就是非零,取表达式2的值,作为整体的值；如果是假,就是零,取表达式3,作为整体的值.
//&a和&b就是取a,b的地址.q=(a<b)?&a:&b=(5<7)?&a:&b=(TRUE)?&a:&b=&a.q指向a
printf("%d %d %d\n",a,b,*q);//a=5,b=7,*q=a=5
int a=3,b=4,*q=&b; *q=a+b;a=5; q=(a
#include void main( ) { int a=3,b=5; int *p,*q; void f1(int x,int y);void f2(int *x,int *y);p=&a; q=&b;f1(*p,*q) ;printf(a=%d ,b=%d
,a,b);f2(p,q);printf(a=%d ,b=%d

,*p,*q);}两
定义int b[3][4],*q[3]; 下列赋值表达式中是正确的A.q=b b.q=*b c.*q=b+1 D.*q=&b[1][2] 为什么呢?A q=bB q=*bC *q=b+1D *q=&b[1][2]
swap交换函数,用指针实现.#include stdafx.hvoid swap(int &a,int &b ){int* p=&a;int* q=&b; int* t ;if(*p>*q){ t=p;p=q;q=t;}//a=*p;//b=*q;}int main(){int a=12;int b= 1;printf(a=%d
b = %d
,a,b);swap(a,b);printf(a=%d
b = %d
,a,b);re

,*p,*q);}两次调用
