String operation

Reading and writing in a C++ program are controlled by ‘cin’ and ‘cout’. While
‘cin’ reads a string in a program, ‘cout’ is responsible for writting that string to
the console window. Program Example 4.35 of a C++ displays name and age. The
output is shown in Figure 4.66.

Program Example 4.35:

Using character to demonstrate string function

#include <iostream>
using namespace std;
int main()
{
char name[10];
int age;
cout<<”Enter your first name and age:”<<endl;
cin>> name>>age;
cout<<”You entered: “<<name<<” “<<age<<endl;
}

Output:
