Taking multiple inputs with whitespaces using cin

I have a simple structure which stores details of a person whose values needs to be initialized through user input. The structure is as follows :

typedef struct {

        char name[20];
        int age;
        char address[50];
        char vehicle[10];
}Runner;

I am using cin to store the value of each Runner but wish to take the inputs (that may contain whitespace in between) using enter key after each value entered.

Below is the code :

Runner run1;

        cout << "Enter name age address vehicle (pressing enter at each instance)" << endl;
        cin >> run1.name >> run1.age >> run1.address >> run1.vehicle ;

It is quite evident that space separated values would be considered as two unique entries.

How do I skip the white-spaces and cin only after enter is pressed. Also if there is another approach to such situations, it would be great to know the same.

As the input may have whitespaces between them, you should use getline function.

cin.getline(run1.name,20);
cin.getline(run1.address,50);
cin.getline(run1.vehicle,10);
cin >> age

But if you want to take the value of age after taking the value of name, then you'll have to do something like this.

cin.getline(run1.name,20);
cin >> run1.age;
cin.getline(dummy,5);    //cin leaves a newline at the buffer. This line of code takes the newline from the buffer.
cin.getline(run1.address,50);
cin.getline(run1.vehicle,10);

cin.getline (name,20);
cin.getline (address,50);
cin.getline (vehicle,10);
cin >> age;
