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

C++ or R? Please tag ⭐⭐⭐ONLY⭐⭐⭐ the relevant programming language. Give an example array.

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")
