Answer 1

In R language, you can check if a vector contains a specific element, like this:

names <- c("Amy", "Penny", "Bernadette")
print(is.element("Penny", names)) #TRUE
print(is.element("Sheldon", names)) #FALSE

Answer 2

C++ or R? Please tag ⭐⭐⭐ONLY⭐⭐⭐ the relevant programming language.

Give an example array.

Answer 3

Ok... look i mean something like
let take c++ as example ok!...

#include <iostream>

using namespace std;

int main()
{
string class1[5] ={"class1","khalid","ali","maab","hibe"};
string class2[5] ={"class2","musa","abdalh","noor","Ahmed"};
string class3[5] ={"class3","noor","hussan","mhmmed","mahmoud"};

// now i want the user to input his
// value (his name that he want to
// know if in the dataset or not)
string name;
cin >> name;

if(name == "khalid"){
cout << elex27[0];
// i can use if statmant like now
// for any arrya thar i have
// but i can do that if i have lot of arrya
}

return 0;
}
So i need some of function or any method can be helpful but by c++ or r

I find that is easy by python...it can be like :
class1 = [1,2,3]
x="what the user inter"
if x in class1
print ("do something")
