Question

Using string functions and all other programming features discussed in the class, write a program that will prompt a user to input their name (first and last). Ex: Please enter your first and last name: John Doe Then, output the string. Next, prompt the user to input their nickname. Ex: Enter your nickname: Rowdy Then modify the name string to consist of the person’s last name comma, nickname (backwards, in all caps, enclosed in double quotes) and first name. Then output the modified string. Ex: Doe, “YDWOR” John Bonus (+10) Output first and last name alternating every two characters: John Doe Ex: JoDohne Tim Wheaterton Ex: TiWhmeaterton NOTE: This program should loop, prompting the user to decide whether or not he or she wishes to enter another name. Ex: Do you wish to enter another name(y/n)?

comment program must have getline and concatenation also in c++

Answer 1

Code:

name.cpp:

#include<iostream>
#include<string>       //to use getline()
#include<algorithm>       //to use reverse()
using namespace std;

int main()
{
   string c="y";       //initialize choice to continue to yes
  
   do
   {
       string name;
       cout<<"Please enter your first and last name: ";
       getline(cin,name);   //take input with space
      
       string first="",last="";   //initialize first and last name to null strings
       int flg=0;                    //flag to indicate end of first name
      
       for(int i=0;i<name.length();i++)   //seperation of first and last name
       {
           if(name[i]==' ')   //when space detected change flag
           {
               flg=1;
               continue;
           }
          
           if(flg==0)       //when flag==0 (no space detected yet) copy characters to first name
           {
               first=first+name[i];
           }
           else           ////when flag==1 (space detected) copy characters to last name
           {
               last=last+name[i];
           }
       }
      
       string nname; //nickname
       cout<<"Enter your nickname: ";
       getline(cin,nname);   //take nickname
      
       reverse(nname.begin(), nname.end());   //reverse nickname
      
       for(int i=0;i<nname.length();i++)   //change case of nickname to UPPER
       {
           if (nname[i]>='a' && nname[i]<='z')
               nname[i] = nname[i] - 32;
       }
      
       name=last+", \""+nname+"\" "+first;       //modify string name as required
       cout<<"Modified String : "<<name<<endl;
      
       string alter="";   //to store alternating characters
       int f=first.length(),i=0;   //initialize counter for first anme and its end
       int l=last.length(),j=0;   //initialize counter for last name and its end
      
       while(i<f||j<l)       //as first name can be small than last name or vice versa hence used || (OR)
       {
           if(i<f)       //to make sure don't copy NULL character '\0'
           {
               alter=alter+first[i];
               i++;
               if(i<f)   //to make sure don't copy NULL character '\0'
               {
                   alter=alter+first[i];
                   i++;
               }
           }
          
           if(j<l)       //to make sure don't copy NULL character '\0'
           {
               alter=alter+last[j];
               j++;
               if(j<l)       //to make sure don't copy NULL character '\0'
               {
                   alter=alter+last[j];
                   j++;
               }
           }
       }
      
       cout<<"Alternating every two character string: "<<alter<<endl;   //Output alternating string
      
       cout<<"Do you wish to enter another name(y/n)? ";   //Ask if you want to continue
       cin>>c;
       cin.ignore();   //used to ignore enter key hitted for next getline()
      
   }while(c=="y");
  
   return 0;
}
