Question
Hi,
For this assignment I have to use vector and I am struggling on where possibly I could apply that in this following code.
USING VECTOR FIELD
USING VECCTORS
IN C++ For your assignment you are writing a number guessing game; with a twist. In your game, they are calculations where the user must guess the missing number(s). The Computer guesses a random calculation "Value1 Operator Value2 = Answer." The computer randomly displays two of the four objects. The Player must guess the remaining two objects. If the player gets one right then the computer says "one is right." The game should continue until the user has provided all the correct calculations.
For Example:
The Computer decides on 12 + 34 = 46. The computer/game then randomly displays Operator is + and Value 2 is 34. The player should now begin guessing numbers. If the player guesses 12 and 20 The computer will respond "one is right" indicating either 12 or 20 are correct.
The game stops when the player guesses 12 and 46 thus giving the random calculation 12 + 34 = 46.

Explanation / Answer
In the following given code, just follow the given below steps to include vector concept in the program :
Step 1: Firstly, Add header file #include <vector>.
Step 2: Secondly, Declare a vector of integers std::vector<int> v; .
Step 3: Thirdly, If you want to use namespace then you can write code as:
#include <vector>
using namespace std;
//.................
vector<int> v;
After you include std once then you no need to write the std again n again....
The answer given by expert is helpfull to you. It also depends on the values which you will be going to give as your input after the execution of program. Vector concept is just used as an array concept works where number of values are to be included. After the inputted value, just follow the working of code.
