What is the purpose of a decision symbol in a flowchart?

To store data values To represent a branching decision based on a condition To denote input/output operations To show the start or end of the process

Correct Answer:

To represent a branching decision based on a condition

Explanation:

The main idea here is how decisions are shown in flowcharts. A decision symbol (the diamond) marks a point where a condition is evaluated and the flow splits based on the result. If the condition is true (or Yes/True), you follow one path; if false (or No/False), you follow another. This lets the chart map out different outcomes without hardcoding every step, guiding the process according to real-time checks. Other symbols handle different roles: storing data uses a data storage symbol, input/output uses a parallelogram, and starting or ending uses an oval. So the diamond’s job is to route the flow according to a conditional test.
