Write a program that lets you know if you can have a key or not, based on your role at the school.
First ask for the user’s role at the school. They can be a student, administrator, or a teacher. (And remember that capitalization is important! ‘Student’ is not the same as ‘student’.)
Example 1: Administrator or Teacher
For example, if this was the input:
Are you an administrator, teacher, or student?: teacher
This should be the output:
Administrators and teachers get keys!
Example 2: Student
And if this was the input:
Are you an administrator, teacher, or student?: student
This should be the output:
Students do not get keys!
(Note: You should also be able to handle a situation where the user enters a value other than administrator, teacher or student and tell them they must be one of the three choices!)
Example 3: Other
If they input anything else:
Are you an administrator, teacher, or student?: secretary
This should be the output:
You can only be an administrator, teacher, or student!
Предположим, что все элементы массива по модулю не превышают одного миллиона, тогда код будет иметь следующую структуру :
#include <iostream>
#include <set>
using namespace std;
signed main(){
set<int> fibs;
fibs.insert(1);
fibs.insert(2);
while(*next(fibs.begin(),fibs.size() — 1) + *next(fibs.begin(), fibs.size() — 2) <= int(1e6))
fibs.insert(*next(fibs.begin(),fibs.size() — 1) + *next(fibs.begin(), fibs.size() — 2));
int n;
cin >> n;
int a[n];
bool f = false;
for(int i = 0; i < n; i++){
cin >> a[i];
if(fibs.find(a[i]) != fibs.end()){
cout << a[i] << » «;
f = true;
}
}
if(!f)
cout << «There are no fibonacci elements in current array»;
}
