The process of making decisions is fundamental in programming, just as it is in real life. A pre-existing condition is evaluated, and a decision is made based on the evaluation. For example, if it is cold outside, a person chooses to wear a coat. If a temperature sensor exceeds a certain threshold, the furnace turns off. In C++, as in other programming languages, a decision construct is used to control the sequence of instructions that are executed under certain conditions. It allows the programmer the power to take certain action based on various input conditions. For example, a grading program will need to assign a certain grade based on a test score.
