Study Notes
Decision Making using If
- If statement is a two-way decision statement used in conjunction with an expression.
- Syntax:
if (test expression) { statement block; } statement-x; - If the test expression is true, the statement block after if is executed, otherwise it is not executed.
If-Else Statement
- Used when there is another set of statements to be executed if the condition is false.
- Syntax:
if (test expression) { statement block1; } else { statement block2; } statement-x;
Nested If-Else Statement
- Used when more than one if-else statement is needed.
- Syntax:
if (test cond1) { if (test expression2) { statement block1; } else { statement block2; } } else { statement block2; } statement-x;
Switch Case Statement
- Used when there are more than one valid choices to choose from.
- Syntax:
switch(expression) { case value-1: block-1; break; case value-2: block-2; break; ... default: default block; break; } statement-x;
Ternary Operator
- Syntax:
Test condition ? expression1 : expression2; - If the test condition is true, expression1 is executed, otherwise expression2 is executed.
- Takes 3 operands: condition, expression1, and expression2.
GoTo Statement
- Used to escape from multiple nested loops or to go to an error handling exit at the end of a function.
- A label is required when using a goto statement.
- Labels have their own namespace and can't clash with variable or function names.
This quiz covers the basics of decision making in programming using if statements. Learn how to execute specific statements based on conditions and loop through statements until certain conditions are met. Explore the syntax and usage of if statements in programming.
