- 54. What is the difference between the top and pop operations of a stack? Group of answer choices The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack and remove it. The top operation removes the top item of the stack. The pop operation returns a reference to the top item on the stack without removing it. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack without removing it. The pop and top operations are doing the same thing which removes the top item of the stack. The pop operation removes the top item of the stack. The top operation returns a reference to the top item on the stack and remove it.assume we use the STL of the stack, with the following code stack<char>s; string word=”stack”; int i; while (word[i]!=0) s.push(word[i]); while (!s.empty()) { Cout<<s.top(); s.pop(); } the output is a. stack b. kcats c. kcsta d. ackassume we use the STL of the stack, with the following code stack<char>s; string word=”stack”; int i; while (word[i]!=0) s.push(word[i]); while (!s.empty()) { Cout<<s.top(); s.pop(); } the output is a. stack b. kcats c. ack d. kcsta
