Consider the following code. In this code the function displayClass(stackClass) is called.

Which of the following code (i) represents the correct implementation of the displayClass function?

#include <stack>

#include <string>

//…(i)… missing code for the function.

int main() {

std::stack<std::string> stackClass; stackClass.push(“John”); stackClass.push(“Peter”); stackClass.push(“Mary”); displayClass(stackClass);

return 0;
