在C++中，如果cout一個(gè)字符數(shù)組的話，那么它會沿著這個(gè)地址，一直輸出這個(gè)字符串，直到遇到'/0'實(shí)際上，C++標(biāo)準(zhǔn)庫中I/O類對輸出操作符<<重載，在遇到字符型指針時(shí)會將其當(dāng)做字符串名來處理，輸出指針?biāo)傅淖址＜热贿@樣，我們就別讓他知道那是字符型指針，所以得進(jìn)行類型轉(zhuǎn)換，即：希望任何字符型的指針變量輸出為地址的話，都要作一個(gè)轉(zhuǎn)換，即強(qiáng)制char *轉(zhuǎn)換成void *

#include<iostream>int main(){const short ITEMS=5;int intArray[ITEMS]={1,2,3,4,5};char charArray[ITEMS]={'L','M','Y','L','R'};int *intPointer=intArray;char *charPointer=charArray;std::cout<<"整形數(shù)組輸出"<<"/n";for(int i=0;i<ITEMS;i++){std::cout<<*intPointer<<"  at   "<<intPointer<<"/n" ;intPointer++;}std::cout<<"字符型數(shù)組輸出"<<"/n";for(int i=0;i<ITEMS;i++){std::cout<<*charPointer<<"  at   "<<charPointer<<"/n" ;charPointer++;}return 0;}

整形數(shù)組輸出1  at   0x29ff002  at   0x29ff043  at   0x29ff084  at   0x29ff0c5  at   0x29ff10字符型數(shù)組輸出L  at   LMYLR@M  at   MYLR@Y  at   YLR@L  at   LR@R  at   R@

對字符型指針進(jìn)行強(qiáng)制類型轉(zhuǎn)換之后：

#include<iostream>int main(){const short ITEMS=5;int intArray[ITEMS]={1,2,3,4,5};char charArray[ITEMS]={'L','M','Y','L','R'};int *intPointer=intArray;char *charPointer=charArray;std::cout<<"整形數(shù)組輸出"<<"/n";for(int i=0;i<ITEMS;i++){std::cout<<*intPointer<<"  at   "<<intPointer<<"/n" ;intPointer++;}std::cout<<"字符型數(shù)組輸出"<<"/n";for(int i=0;i<ITEMS;i++){std::cout<<*charPointer<<" at   "<<(void *)charPointer<<"/n" ;charPointer++;}return 0;}

整形數(shù)組輸出1  at   0x29ff002  at   0x29ff043  at   0x29ff084  at   0x29ff0c5  at   0x29ff10字符型數(shù)組輸出L at   0x29fef0M at   0x29fef1Y at   0x29fef2L at   0x29fef3R at   0x29fef4
