#include <iostream>
#include <stack>
using namespace std;
int main()
{
string sname, saddress, sname_teacher;
int snumber_classrooms;
double ratio, snumber_students, snumber_teachers;
//Entering data of school
cout << "Enter school data: \n";
cout << "Enter name of school : ";
cin >> sname;
cout << "Enter an address of school : ";
cin >> saddress;
cout << "Enter number of classrooms of the school : ";
cin >> snumber_classrooms;
cout << "Enter number of students of the school : ";
cin >> snumber_students;
cout << "Enter number of teachers of the school : ";
cin >> snumber_teachers;
//check if number of teachers < 20 or not
if (snumber_teachers > 20) {
while (snumber_teachers > 20) {
cout << " The number of teachers should not be more than 20 teachers. \n";
cout << "Enter number of teachers of the school : ";
cin >> snumber_teachers;
}
}
//check if number of teachers : number of students < (1/50=0.02)
ratio = snumber_teachers / snumber_students;
while (ratio < 0.02) {
cout << " The number of teachers should not be less than 1/50 number of students. \n";
cout << "Enter number of teachers of the school : ";
cin >> snumber_teachers;
ratio = snumber_teachers / snumber_students;
}
// Entering names of teachers
int snumber_teachers2 = snumber_teachers;
stack<string> names;
for (int i = 0; i < snumber_teachers2; i++) {
cout << "Enter names of teachers : ";
cin >> sname_teacher;
names.push(sname_teacher);
}
cout << " \n The Data of shool has entered succedly :)\n \n";
// Printing data of school
cout << " _______________________The Data of school are_______________________ \n";
cout << " name : " + sname << endl;
cout << " address " + saddress << endl;
cout << " classrooms : " << snumber_classrooms << endl;
cout << " students : " << snumber_students << endl;
cout << " teachers : " << snumber_teachers << endl;
cout << " names of teachers : \n";
// Printing content of stack
while (!names.empty()) {
cout << ' ' << names.top();
names.pop();
cout << "\n";
}
return 0;
}

Answer 1

You want to receive several inputs for teacher names, but only prompt "Enter names of teachers : " once.
So change
for (int i = 0; i < snumber_teachers2; i++) {
cout << "Enter names of teachers : ";
cin >> sname_teacher;
names.push(sname_teacher);
}
to
cout << "Enter names of teachers : ";
for (int i = 0; i < snumber_teachers2; i++) {
cin >> sname_teacher;
names.push(sname_teacher);
}
I.e. keep what you want to repeat inside the loop,
but move what you only want once outside.
