Purpose of Conditional Flow Control

Why do programmers use conditional flow control statements like if and switch in their code?

A To decide which block of code to run based on certain conditions

B To repeat a block of code multiple times automatically

C To store multiple values in a single variable

D To define new data types for organizing data

💡 Hint

Think about how a program can choose different paths depending on information it has.

Conditional flow control lets a program choose what to do next based on conditions. This helps the program make decisions, like a fork in a road.

Output of Conditional Statement

What will be the output of this C# code?

C Sharp (C#)

int temperature = 30;
if (temperature > 25)
{
    Console.WriteLine("It's hot outside.");
}
else
{
    Console.WriteLine("It's cool outside.");
}

A It's cool outside.

B It's hot outside.

C No output

D Compilation error

💡 Hint

Check the condition temperature > 25 and see if it is true or false.

The variable temperature is 30, which is greater than 25, so the if block runs and prints "It's hot outside.".

Switch Statement Output

What will this C# program print?

C Sharp (C#)

int day = 3;
switch (day)
{
    case 1:
        Console.WriteLine("Monday");
        break;
    case 2:
        Console.WriteLine("Tuesday");
        break;
    case 3:
        Console.WriteLine("Wednesday");
        break;
    default:
        Console.WriteLine("Another day");
        break;
}

A Wednesday

B Compilation error

C Another day

D Tuesday

💡 Hint

Look at the value of day and match it with the correct case.

The variable day is 3, so the case 3 block runs and prints "Wednesday".

Identify the Error in Conditional Code

What error will this C# code cause?

C Sharp (C#)

int number = 10;
if (number > 5)
{
    Console.WriteLine("Number is greater than 5");
}

A No error, code runs fine

B Missing parentheses error

C Missing semicolon error

D Variable not declared error

💡 Hint

Check the end of the first line for syntax mistakes.

The first line is missing a semicolon at the end, causing a syntax error.

Why Conditional Flow Control is Essential in Programs

Which statement best explains why conditional flow control is essential in programming?

A It automatically fixes errors in the code during execution

B It helps programs store large amounts of data efficiently

C It allows programs to perform repetitive tasks without stopping

D It enables programs to make decisions and respond differently based on input or state

💡 Hint

Think about how programs can behave differently in different situations.

Conditional flow control lets programs choose different actions depending on conditions, making them flexible and responsive.
