It turns out that std::cin only accepts two inputs for Boolean variables: 0 and 1 ( not true or false). Any other inputs will cause std::cin to silently fail. In this case, because we entered true, std::cin silently failed and didn’t assign a value to variable b. Consequently, when std::cout printed a value for b. C programs have to make decisions. A program that can’t make decisions is of limited use. Invariably a computer program gets to the point where it has to figure out situations such as “Do this if the a variable is less than some value; do that other thing if it’s not.” The ability to make. The break statement has the following two usages in C −. When the break statement is encountered inside a loop, the loop is immediately terminated and program control resumes at the next statement following the loop. It can be used to terminate a case in the switch statement (covered in the next chapter). If you are using nested loops (i.e., one loop inside another loop), the break.

An if statement can be followed by an optional else statement, which executes when the Boolean expression is false.

The syntax of an if...else statement in C programming language is −
If the Boolean expression evaluates to true, then the if block will be executed, otherwise, the else block will be executed.

C programming language assumes any non-zero and non-null values as true, and if it is either zero or null, then it is assumed as false value.

If...else if...else Statement
An if statement can be followed by an optional else if...else statement, which is very useful to test various conditions using single if...else if statement.
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 the remaining else if's or else's will be tested.
