Question

I'm new in C++. I create a project that ask user to input their name, age, handphone number and university.

The code seems like this:

#include<iostream>
#include<iomanip>
#include<vector>

using namespace std;

int main(){
vector<string>name;
vector<string>age;
vector<string>hpno;
vector<string>university;

string sname, sage, shpno, suniversity;

cout << "Enter name:" << endl;
getline(cin, sname);
name.push_back(sname);

cout << "Enter age:" << endl;
getline(cin, sage);
age.push_back(sage); 

cout << "Enter phone number:" << endl;
getline(cin, shpno);
hpno.push_back(shpno);

cout << "Enter university:" << endl;
getline(cin, suniversity);
university.push_back(suniversity);

cout << "Name" <<" "<< "Age" <<" "<< "Handphone Number" <<" "<< "University" 
     <<endl;    

for (int j = 0 ; j <= name.size() - 1 ; j++){
cout << name[j] << " " << age[j] << " " << hpno[j] << " " << 
university[j]<<endl;}

}

Let say the user input is like this:

Name: John Cena
Age: 20
Phone Number: 1234568903
University: Multimedia Univeristy

The Output that I want is like this:
Name Age Phone Number University John Cena 20 1234568903 Multimedia University

But the Output that I get is like this:
Name Age Phone Number University John Cena 20 1234568903 Multimedia University

How to make the width of header synchronize with the width of content ?

I think you should set the width. For that in c++, there is setw(). use that

Why don't you explain its usage in your answer, instead? – Bob__ Sep 23 '17 at 14:58

First include the missing <string> header, don't rely on free rides from other headers. Then utilize the std::left and std::setw stream manipulators on both the title and the data output:

std::cout << std::left << std::setw(10) << "Name"
    << std::setw(10) << "Age"
    << std::setw(20) << "Handphone Number"
    << std::setw(10) << "University"
    << std::endl;

for (int j = 0; j <= name.size() - 1; j++){
    cout << std::setw(10) << name[j]
        << std::setw(10) << age[j] 
        << std::setw(20) << hpno[j] 
        << std::setw(10) << university[j] << endl;
}

Note: some manipulators are persistent and need to be included only once, others are not and need to be included multiple times. Avoid the using namespace std.

In this case you need std::setw(), std::setfill('*'). Follow this links and read documentation.

C++ can setw and setfill pad the end of a string?
