Question

for c++ pls

4.10 LAB: Name format Many documents use a specific format for a person's name. Write a program whose input is: firstName middleName lastName, and whose output is: lastName, firstName middlelnitial. Ex: If the input is Pat Silly Doe, the output is: Doe, Pat S. If the input has the form firstName lastName, the output is lastName, firstName. Ex: If the input is: Julia Clark, the output is: Clark, Julia

Answer 1

I have provided the proper commented and indented code with proper screenshots, so that it may further help you to indent the code. Here we have used string streams to separate different parts of the name. String streams are similar to standard input stream just we take the input as strings here.

NOTE: You can compile the code using "g++ filename.cpp" command and run the same with "./a.out" command without the quotes.

CODE:

-----------------------------------------------------------------------------------------------------------

//Including the necessary libraries for I/O and stringstreams
#include<iostream>
#include<sstream>
using namespace std;

//The main Function
int main(){
    //Declaring the string to take the input name
    string str;

    //Taking the name as a whole line
    getline(cin,str);

    //declaring the string array to store different part of the names
    string name[3];

    //count variable to keep track of how many parts does the name have
    int count_name = 0;

    //Initializing the stringstream to take the input from the name i.e 'str'
    //and to seperate different parts of the name
    stringstream iss(str);

    //temporary string to store the part of name
    string temp;

    //Extracting different parts of name from the str with the help of loop
    while(iss>>temp){
        name[count_name] = temp;
        count_name++;
    }
    //Checking the different conditions for the number of subparts of the name
    //and printing the appropriate result
    if(count_name == 1){
        cout<<name[0]<<endl;
    }
    else if(count_name == 2){
        cout<<name[1]<<", "<<name[0]<<endl;
    }
    else if(count_name == 3){
        cout<<name[2]<<", "<<name[0]<<" "<<name[1][0]<<"."<<endl;
    }
    return 0;
}

Output:

Pan Silly Doe Doe, Pan s.

Julia Clarke Clarke, Julia

Happy Coding!
