If +1 to Variable

Question

Given the following code:

int number = 50;

Which code will display "yes" and add one to the number variable if the value stored in the number variable is greater than or equal to 50?

1. if ( number > 50)
{
cout << "yes" << endl;
number = number + 1;
}

2. if ( number >= 50)
cout << "yes" << endl;
number = number + 1;

3. if ( number >= 50)
{
cout << "yes" << endl;
number = number + 1;
}

4. if ( number <= 50)
{
cout << "yes" << endl;
number = number + 1;
}

Please give me the correct option when explaining. 2, 3, and 4 all give me a yes and a 51.

Answer 1

3 is correct.
1 checks greater than only and 4 checks less than or equal. So both are incorrect.
Although 2 checks greater than and equal, since the increment statement is outside the if statement it'll always increment the number even if the condition is false.
