In programming, decision-making plays a crucial role in determining the logical flow of a program. Sequentially executing lines of code may not always be sufficient, as different actions need to be taken based on certain s. To achieve this, programmers often utilize and mechanisms.
This is where selection constructs such as the "" and the "" come into play. An "if statement" is used to evaluate a condition and execute a specific block of code only if the condition evaluates to true. It provides a way to control the flow of execution by branching to different paths based on the result of the condition.
Similarly, a "switch statement" evaluates an expression and selects one of many possible s based on the expression's value. It acts as a multi-branching mechanism, allowing the program to choose a specific block of code to execute from a range of possibilities.
Conditions in both "if statements" and "switch statements" are typically expressed in terms of s, which are data types that can have two values: true or false. When a condition evaluates to true, the associated block of code is executed. However, if none of the conditions are met, there is often a need for a fallback action, known as the "" in a switch statement or the lack of additional s.
