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.
