Control Statements (if,switch case & loops)

Control Statements:

Control Statements are used to control the flow of program. They allow us to make decisions, iterations, and perform different actions based on conditions. Some Control statements include:

1. If Statements:

The if statement is used to execute a block of code if a certain condition is true.

Syntax:

if (condition)
{
      // code
}

2. If-else Statements:

The if-else statement is used to execute one block of code if a condition is true and another block of code if the condition is false.

Syntax:

if (condition)
{
    // Code executed when condition is true
}
else
{
    // Code executed when condition is false
}

3. If else if else

The if-else if-else statement is used when there are multiple conditions to be checked.

Syntax:

if (condition1)
{
    // Code executed if condition1 is true
}
else if (condition2)
{
    // Code executed when condition2 is true
}
else
{
    // Code executed when none of the conditions are true
}

4. switch Statement:

The switch statement is used to evaluate a variable against multiple possible constant values.

Syntax:

switch (variable)
{
    case value1:
        // Code to be executed if variable equals value1
        break;
    case value2:
        // Code to be executed if variable equals value2
        break;
    // More cases...
    default:
        // Code to be executed if none of the cases match
        break;
}

5. while Loop:

The while loop is used to repeatedly execute a block of code as long as a condition is true.

Syntax:

while (condition)
{
    // Code to be executed in each iteration
}

6. do-while Loop:

The do-while loop is similar to the while loop, but it guarantees that the block of code is executed at least once before checking the condition.

Syntax:

do
{
    // Code to be executed in each iteration
} 
while (condition);

7. for Loop:

The for loop is used to iterate a specific number of times.

Syntax:

for (initialization; condition; increment)
{
    // Code to be executed in each iteration
}

8. foreach Loop:

The foreach loop is used to iterate over elements in a collection (e.g., arrays, lists).

Syntax:

foreach (var item in collection)
{
    // Code to be executed for each item in the collection
}
