Sequence structure cannot handle all types of tasks. These can be achieved by using decision structure. An example of decision structure is “if” statement.
“if” statement:
“if” statement is used to make a decision structure, which permits the program to hold more than one path of execution.
- The indented statement is executed only when the condition is “true”.
