1. the prototype of the known class MyString is:

Class MyString
{
Public: MyString (const char * str = NULL); // common Constructor
MyString (const MyString); // copy the constructor
~ MyString (void); // destructor
MyString & operator = (const MyString); // value assignment Constructor
Private: char * m_c_data; // used to save strings

}; Write the above four functions of MyString.

Programmer interview guide p112

Class MyString {public: MyString (const char * str = NULL); // normal constructor MyString (const MyString & other); // copy constructor ~ MyString (void); // destructor MyString & operator = (const MyString & other); // value assignment constructor private: char * m_data; // used to save the string }; myString: MyString (const char * str) // constructor {if (str = NULL) {m_data = new char [1]; * m_data = '\ 0 ';} else {int length = strlen (str); m_data = new char [length + 1]; strcpy (m_data, str) ;}} MyString ::~ MyString (void) // destructor {delete [] m_data; // Since m_data is an internal data type, you can also write delete m_data;} MyString :: myString (const MyString & other) // copy the constructor {int length = strlen (other. m_data); m_data = new char [length + 1]; strcpy (m_data, other. m_data);} MyString & MyString: operator = (const MyString & other) // value assignment function {if (this = & other) // check the self-assigned return * this; delete [] m_data; // release the original memory resource int length = strlen (other. m_data); // allocate new memory resources and copy the content m_data = new char [length + 1]; strcpy (m_data, other. m_data); return * this; // return the reference of this object}

2. merge the two data sequences into a data with no identical elements in sequence.

For example, s1 [5] = {, 24}, s2 [5] = {, 19, 25}
Output 10, 14, 24, 25, 62 after execution

Note: library functions cannot be used.

#include<iostream>using namespace std;int main(){int s1[5]={23,14,62,57,24},s2[5]={14,19,10,14,25};int s3[10],i,j,k,t;int flag;s3[0]=s1[0];k=1;for(i=1;i<5;i++){flag=1;for(j=0;j<k;j++){if(s1[i]==s3[j]){flag=0;break;}}if(flag==1)s3[k++]=s1[i];}for(i=0;i<5;i++){flag=1;for(j=0;j<k;j++){if(s2[i]==s3[j]){flag=0;break;}}if(flag==1)s3[k++]=s2[i];}for(i=0;i<k-1;i++){for(j=0;j<k-1-i;j++){if(s3[j]>s3[j+1]){t=s3[j];s3[j]=s3[j+1];s3[j+1]=t;}}}for(i=0;i<k;i++){cout<<s3[i]<<" ";}return 0;}

3. print A matrix of N * N. N is the number of characters on each side (3 <N <20). The outermost layer must be "A" and the second layer must be "B ", print numbers 0, 1, 2, 3 ,...... Example: when n = 5, print the following figure
AAAAA
ABBBA
AB0BA
ABBBA

AAAAA

#include<cstring>#include<iostream>using namespace std;int main(){int N;int i,j,k,m;char a[20][20];cin>>N;for(i=0;i<(N+1)/2;i++){ if(i==0) {for(j=0;j<N;j++)a[j][i]=a[i][j]=a[j][N-i-1]=a[N-i-1][j]='A';}else if(i==1){for(j=1;j<N-i;j++)a[j][i]=a[i][j]=a[N-i-1][j]=a[j][N-i-1]='B';}else {for(j=i;j<N-i;j++)a[j][i]=a[i][j]=a[N-i-1][j]=a[j][N-i-1]=i-2+'0';}}for(i=0;i<N;i++){for(j=0;j<N;j++){cout<<a[i][j]<<" ";}cout<<endl;}return 0;}

Some websites can be opened by others, and I cannot open them. On the page, the cheetah browser + Kingsoft + mobile broadband solution is displayed.

Hello, this is why IE cannot display this webpage. We recommend that you switch to quick mode to try it and see if it can be opened normally? If the rapid mode still does not work, it is not a browser problem, it may be related to your local network restrictions, it is recommended that you pay attention to security when accessing such websites.

If you still have any questions, please contact Kingsoft Enterprise

Jinshan Network (cheetah mobile) has staff canteen or Chinese food and dinner subsidies?

Hello, this is acceptable. I personally estimate that his facilities should be well-developed.
