Answer 1

//program to print initials of a name
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char a[100];
char b[100];
int i;
int j=2;
printf(“Enter a name \n”);
gets(a);
b[0]=a[0];
b[1]=’.’;
for(i=0;i<strlen(a);i++);
{
if(a[i]==’ ‘)
{
b[j]=a[i+1];
j++;
b[j]=’.’;
j++;
}
}
for(i=strlen(a);a[i]!=’ ‘;i--)
j=j-2;
for(i=i+1;i<strlen(a);i++)
{
b[j]=a[i];
j++;
}
b[j]=’\0’;
printf(“The initial is : \n”);
for(i=0;i<strlen(b);i++)
{
if(b[i]==’ ‘)
i++;
else
printf(“%c”,b[i]);
}
}

Answer 2

#include <iostream>
#include <iterator>
#include <sstream>
#include <vector> 

// vector of desired type:

template<typename T>

std::vector<T> LineSplit(const std::string& line) {

std::istringstream is(line);

return std::vector<T>(std::istream_iterator<T>(is), std::istream_iterator<T>());

 }

class Names

{

private: std::vector<std::string> full_name_;

void TakeInput()

{ std::cout << "Enter the name: " << std::endl;

std::string input;

getline(std::cin,input);

full_name_ = LineSplit<std::string>(input);

}

 void DisplayInitialsOfFirstNames() const {

std::cout << "Mr. ";

for (std::size_t i = 0; i < full_name_.size()-1; ++i) {

std::cout << full_name_[i][0] << ". ";

}

};

void DisplayLastName() const {

std::cout << full_name_.back() << std::endl;

}

public:

void work() {

TakeInput();

DisplayInitialsOfFirstNames();

DisplayLastName();

};

};

int main(){

Names n;

n.work();

}
