1. (7 points) Define a class named “IntegerVariable” that manages a variable name (string) and an integer value. The data members must be declared as "private." The class must provide at least the following methods: a. "isSame VariableName" that compares with another Integer Variable object. It returns true if they both have the same variable name, and false otherwise. b. "toString" method to return string representing the variable information (name and value) c. "getValue” to return its integer value. d. "getVarName" to return its name e. "is Bigger" to compare with another Integer Variable. It returns true if its value is bigger than the other and false otherwise.

#include <iostream>
#include <vector>
#include <string>

using namespace std;

class IntegerVariable {
private:
    string variable_name;
    int value;
public:
    IntegerVariable() {

    }

    IntegerVariable(string variableName, int value) : variable_name(variableName), value(value) {

    }

    bool isSameVariableName(IntegerVariable var) {
        return variable_name == var.variable_name;
    }

    string toString() {
        return variable_name + " - " + to_string(value);
    }

    int getValue() {
        return value;
    }

    string getVarName() {
        return variable_name;
    }

    bool isBigger(IntegerVariable var) {
        return value > var.value;
    }
};

IntegerVariable *getSmallestVar(vector<IntegerVariable *> v) {
    IntegerVariable *min = v[0];
    for (int i = 0; i < v.size(); ++i) {
        if (min->isBigger(*v[i]))
            min = v[i];
    }
    return min;
}

int main() {
    vector<IntegerVariable *> v;
    v.push_back(new IntegerVariable("var1", 10));
    v.push_back(new IntegerVariable("var1", 2));
    v.push_back(new IntegerVariable("var1", 7));
    v.push_back(new IntegerVariable("var1", 4));
    v.push_back(new IntegerVariable("var1", 3));
    cout << getSmallestVar(v)->getValue() << endl;
    return 0;
