在我的C++學習複製構造函數的使用等等,我們得到了一個我們要完成的程序的模板,但是我的輸出在我的輸出流中引入了時髦的asci字符。C++,Odd Asci輸出與我的程序
繼承人我的主類:
#include <iostream>
using namespace std;
#include "Contact.h"
using namespace sict;
int main(){
Contact c("Empty Contact", 3);
c.display();
cout << "Enter Contact information: " << endl;
c.read();
c.display();
cout << endl;
for (int i = 0; i < 1000000; i++){
Contact temp("Testing the contact with a looooong "
"name that should be taken care of", 20);
if (!(i % 100000)){
cout << i << ":" << endl;
temp.display();
}
}
return 0;
}
Contact.cpp:
#include <cstring>
#include <iostream>
#include "Contact.h"
using namespace std;
namespace sict{
void Contact::display()const{
//display the name and go to new line
cout<< _name << endl;
// loop through elements of _pn up to _noPN and display them one by one
for(int i = 0; i < _noPN ; i++){
_pn[i].display();
}
// draw a 40 char line using '-' and go to new line
cout<<"----------------------------------------"<<endl;
}
Contact::Contact(){
_pn = nullptr;
}
Contact::Contact(const char* name, int number){
strncpy(_name, name,40);
_pn = new PhoneNumber[number];
_noPN = number;
}
Contact::~Contact(){
delete[] _pn;
}
void Contact::read(){
cout << "Contact Name: ";
cin.getline(_name, 41, '\n');
cout << "Please enter " << _noPN << " phone numbers: " << endl;
for (int i = 0; i < _noPN; i++){
cout << i + 1 << ": ";
_pn[i].read();
}
}
bool Contact::isEmpty()const{
return _pn == (PhoneNumber*)0;
}
void Contact::setEmpty(){
_name[0] = 0;
_noPN = 0;
_pn = (PhoneNumber*)0;// same as _pn = nullptr;
}
}
輸出故障:
Empty Contact

正如你所看到的,那裏有在名稱末尾添加一些ASCII字符
我可以添加程序的其餘部分但它是安靜冗長的,如果要求它我會編輯這篇文章,將它們添加。
沒有'Contact'類的定義,我們真的不能幫助。這顯然是問題所在。 – owacoder
您需要顯示'Contact'構造函數 - 問題很可能存在(並且可能缺少字符串的null終結符)。 – Rostislav
對不起,添加它。 – andirew
