How to use IF statements C++

How to use IF statements C++. To make a menu choice, we need an IF statement. This statement is used to solve the problem in making a decision among all these existing conditions. Sintax like this:


  if (condition)

{

  statement;

}


IF statements ELSE statements can also be added as an alternative if the condition is not fulfilled .. Sintaxnya:


if (condition)

     statement_1;

else

     statement_2;



In the program menu of options that we use this time, the IF statement is used to select one of the selected menu .. example, if we choose a menu, it will start a new game (New Game) .. if you select menu 2, then it will start a saved game (Load Game), if you select menu 3, it will come out of the game (Exit) ..

In the program, source code would be like this ..
#include <iostream>

using namespace std;


void main()
{
   
    int a;
    int b;
    int c;
    int d;
    int e;
    int f;
    int g;
       
   
   
    cout << "Enter Fist Number: ";
    cin >> a;
    //cout << a << "\n";
    cout << "Enter Second Number: ";
    cin >> b;
    //cout << a << "\n";
    cout << "Enter Next Number: ";
    cin >> c;
    //cout << a << "\n";
    cout << "Enter Next Number: ";
    cin >> d;
    //cout << a << "\n";
    cout << "Enter Next Number: ";
    cin >> e;
    //cout << a << "\n";
    cout << "Enter Next Number: ";
    cin >> f;
    //cout << a << "\n";
    cout << "Enter Next Number: ";
    cin >> g;
    //cout << a << "\n";
    if (a=b=c=d=e=f=g)
    {
        "Cannot Enter Same Numbers! ";

    }

}
