Question on getline c++

[LordRogue90]

Whenever i input something before the getline. It skips my Enter Student Name: and continues to Enter School Name: Why is that?
it would just show "Enter Student Name: Enter School Name: "

#include <iostream>
#include <string>
#include <stdlib.h>        
using namespace std;

struct StudentProfile 
{
  string student;
  string school;
  string gender;
  int seatnumber;
} Student [25];

void display(int count)
{
	cout<<Student[count].seatnumber<<".) ";
    cout<<Student[count].student<<endl;
}

void seat(int count)
{
	Student[count].seatnumber=count+1;
	display(count);
	
}

int main ()
{
	char choose;
	cout<<"-----------------------Classroom Seat Assignment Program-----------------------";
	cout<<"Program Description:"<<endl;
	cout<<"The program takes 25 students, each with a name, school, and gender."<<endl;
	cout<<"The program will not allow two students with the same school and gender to seat"; 
	cout<<"side-by-side. The program will then display the results by row. "<<endl<<endl;

Consider this code:

#include <iostream>
#include <string>

using namespace std;

int
main()
{
    int i;
    string str;
    cout << "Enter integer: ";
    cin >> i;
    cout << "Enter string: ";
    getline(cin, str);

    cout << "integer is " << i << ". string is " << str << '\n';
    return 0;
}

When you run it, it prompts for an integer, then prints "Enter string:" and doesn't wait for you to enter a line. The reason is that there is already a line in the input buffer. The line is the newline you typed after entering your integer (and anything else before the newline). To see this, run the program and give the input

5 Look here is the line

Enter integer: 5 Look here is the line
Enter string: integer is 5. string is  Look here is the line

To fix this, you have to ignore anything after the "5" through to the newline:

#include <iostream>
#include <string>
#include <limits>

using namespace std;

int
main()
{
    int i;
    string str;
    cout << "Enter integer: ";
    cin >> i;
    cin.ignore(numeric_limits<streamsize>::max(), '\n');
    cout << "Enter string: ";
    getline(cin, str);

    cout << "integer is " << i << ". string is " << str << '\n';
    return 0;
}
