Struck with input

[Hajo93]

I'm in the process of creating a code. Where I can enter student number, name and age. It works as long as I just type in a first name like Mark, if I type in a first name and a last name like Mark Webber then everything will go worng, can anyone help me?

  struct student_t
{
    char s[50];
    int a;
    int i;
};

int main() {

    student_t p1;

    printf("Student number?");
    scanf("%d",&p1.i);
    printf( "Name?");
    scanf("%s",&p1.s);
    printf("age?");
    scanf("%d",&p1.a);


    printf("Student id: %d" ,p1.i);
    printf("\n Name: %s",p1.s);
    printf("\n Age: %d", p1.a);


    return 0;

Just use C++.

#include <iostream>
#include <string>

using std::string;
using std::cin;
using std::cout;

struct student_t
{
    string name;
    int age;
    int id;
};

int main() {

    student_t p1;

    cout << "Student number?";
    cin >> p1.id;

    cout << "Student name?";
    cin.ignore(); // clear the endline that's in the input buffer
    std::getline (cin, p1.name);

    cout << "Student age?";
    cin >> p1.age;

    cout << "Student id: " << p1.id << '\n'
         << "Student name: " << p1.name << '\n'
         << "Student age: " << p1.age << '\n';
   
    return 0;
}
