C++ Conditional and Loop Statements - RECITATION

What is the syntax for the if statement in C++?

• if {condition} then {code block}

• if (condition) { code block to be executed if the condition is true }

• if (condition) { // code block to be executed if the condition is true }

• if (condition) then {code block}

How do you declare a decinal variable in C++?

• float value;

• int num;

• string name;

• bool flag;

What is the purpose of the '&&' operator in C++?

• Logical AND operation

• Bitwise OR operation

• Addition operation

• Assignment operation

Explain the difference between '==' and '=' in C++.

• '==' is used for logical operations, and '=' is used for arithmetic operations.

• '==' and '=' are interchangeable in C++.

• '==' is the assignment operator, and '=' is the equality operator.

• '==' is the equality operator, and '=' is the assignment operator.

When would you use the 'switch' statement in C++?

• When you want to define a function with multiple return statements.

• When you have multiple conditions to check against a single variable.

• When you want to execute a block of code only if a condition is true.

• When you need to loop through a block of code multiple times.

What is the syntax for the 'for' loop in C++?

• for(initialization; condition; increment) [ // code to be executed ]

• for(initialization; condition; update) { // code to be executed }

• for(initialization; condition; increment) // code to be executed

• for(initialization; condition; increment) { // code to be executed }

What does the '++' operator do in C++?

• It increments the value of the variable by 1.

• It assigns the value of the variable to 0.

• It decrements the value of the variable by 1.

• It multiplies the value of the variable by 2.

How do you use the 'while' loop in C++?

• Use 'if' statement with a counter

• Example: int i = 0; while (i < 5) { cout << i << endl; i++; }

• Use 'for' loop instead

• Use 'do-while' loop

What is the '||' operator used for in C++?

• Assignment operator

• Bitwise OR operator

• Logical OR operator

• Ternary operator

Explain the concept of 'nested if' statements in C++.

• Nested if statements in C++ are used to evaluate conditions in parallel

• In C++, nested if statements are used to evaluate multiple conditions sequentially, where the inner if statement is checked only if the outer if statement is true.

• In C++, nested if statements are used to evaluate conditions in reverse order

• Nested if statements in C++ are used to skip the outer if statement if the inner if statement is true
