Control statements are used to decide the program execution order based on some conditions.
It is also called decision making statements.
Let’s write a program for dividing two integers.
But, if we divide a number by 0, program execution will stop as its undefined behavior.
Here, we must decide and restrict the execution of dividing code, if the divisor is zero.
Dividing a number by zero is undefined.
So, the execution order will be,
If divisor is zero
Don’t execute division statement.
Let’s discuss about it one by one with examples.
