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!
#include <iostream.h>
#include <iomanip.h>
#include <math.h>
int main()
{
int a[10], k,n,i,j;
cout<<«Vvedite k:»<<endl;
cin>>k;
cout<<«Vvedite elementy:»<<endl;
for(i=0;i<k; i++)
cin>>a[i];
cout<<«Vvedite n:»<<endl;
cin>>n;
for(i=n-1;i>0;i—)
{
j=a[i];
a[i]=a[i-1];
a[i-1]=j;
}
for(i=0;i<k;i++)
cout<<«Result»<<a[i]<<endl;
return 0;
}
Ответ:
#include <iostream>
int arr[100];
int i, n;
int main(int, char **) {
std::cin >> n;
for (int i = 0; i < n; ++i) {
std::cin >> arr[i];
}
std::cout << arr[0];
for (int i = 1; i < n; ++i) {
std::cout << ‘ ‘ << arr[i];
}
std::cout << std::endl;
}
