Use if-else, if-else with initializer, and if-constexpr statements to control conditional branching.
When using if , else if , else statements there are few points to keep in mind.An if can have zero or one else's and it must come after any else if's. An if can have zero to many else if's and they must come before the else. Once an else if succeeds, none of he remaining...
They are referred to as if-else conditional statements or if-else C++ for short.In this article, we will examine the different types of decision-making statements in C++ programming. These include simple if statements, if-else statements, nested if, if else, if ladder, and jump statements. ...

Ladder if-else statement example in C++: program to enter a character and validate whether it is an alphabet or digit, here we are using ladder if-else (multiple if-else) form of conditional statements in C++.
