head = top = new int 与 head =new int ;top=new int; 两者有区别吗?
head = top = new int 与 head =new int ;top=new int; 两者有区别吗?
head = top = new int 与 head =new int ;top=new int; 两者有区别吗?
肯定有区别,
前面一个语句 head,p指向同一个内存块
后面指针 head,p 指向不同的内存块
head = top = new int 与 head =new int ;top=new int; 两者有区别吗?
每一步都说的什么,#include using namespace std; const int people = 17; struct outt { outt *next; bool go; int num; }; int main( ) { outt *p,*head; int i,n = 0,t = 0; head = new outt; head->go = true; head->num = 1; p = head; for ( i = 1; i < p

求用以下类似程序编一个可以计算括号的计算器#include #define smax 10#define emax 255int power(int x,int y){int t,s=1;for (t=0; t=48 && ex[i]=rinput && rtop!=0){//计算//数字出战top=top-1;x=s[top];top=top-1;y=s[top];s[top]=calc
第一行 type TYPE *creat(int n) { struct stu *head,*pf,*pb; int i; for(i=0;i
动画《chaos;head》中的 如题funˆ10×intˆ40=Ir2
最后一行如何解释int *i,j; i = new int(0);j = 0;int *&y = i; //不懂?
当前月份如何表示?int a = (int)(new Date().getTime()/365/24/3600/1000+1970);
java 语句int a[][]=new int[][3]哪里错了啊?
c语句中,这句话是什么意思?int *p=new int[5];
s.top = s.base + s.stacksize;之前是指针,到最后是怎么完成相加的?typedef struct sqstack{ int *base; int *top; int stacksize;}sqstack;sqstack s;之前是指针,到最后是怎么完成相加的?

C++指针问题 error C2100:illegal indirectionint* label;label=new int[20];label=new int[20];for(int i=0;i
java里 最好举个例子.int[][] 又表示什么?int [] [] pas=new int [6] [];pas=new也理解不了
