Decision Making statements

Decision statements are used to control the flow of a program based on conditions.

If…else: The if…else Statement enables the execution of different blocks of code depending on a condition.

C++

if (condition) {
    // code to execute if condition is true
} else {
    // code to execute if condition is false
}

if (condition) {
    // code to execute if condition is true
} else {
    // code to execute if condition is false
}

Java

if (condition) {
    // code to execute if condition is true
} else {
    // code to execute if condition is false
}

Python

if condition:
    # code to execute if condition is true
else:
    # code to execute if condition is false

if…else if… : The if…else if…else statement allows checking multiple conditions one, after another.

C++

if (condition1) {
    // code to execute if condition1 is true
} else if (condition2) {
    // code to execute if condition2 is true
} else {
    // code to execute if all conditions are false
}

if (condition1) {
    // code to execute if condition1 is true
} else if (condition2) {
    // code to execute if condition2 is true
} else {
    // code to execute if all conditions are false
}

Java

if (condition1) {
    // code to execute if condition1 is true
} else if (condition2) {
    // code to execute if condition2 is true
} else {
    // code to execute if all conditions are false
}

Python

if condition1:
    # code to execute if condition1 is true
elif condition2:
    # code to execute if condition2 is true
else:
    # code to execute if all conditions are false

JavaScript

let condition1 = true; 
let condition2 = false; 

if (condition1) {
    console.log("Condition 1 is true.");
} else if (condition2) {
    console.log("Condition 2 is true.");
} else {
    console.log("All conditions are false.");
}

Switch Statements: The switch statement is utilized to create branches based on the value of an expression.

C++

switch (expression) {
    case value1:
        // code block
        break;
    case value2:
        // code block
        break;
    default:
        // code block
}

switch (expression) {
    case value1:
        // code block
        break;
    case value2:
        // code block
        break;
    default:
        // code block
}

Java

switch (expression) {
    case value1:
        // code block
        break;
    case value2:
        // code block
        break;
    default:
        // code block
}

Python

def switch(someCase):
    if case1:
        // code block
    elif case2:
        // code block
    elif case3:
        // code block
    else: 
        // code block

JavaScript

switch (expression) {
    case value1:
        // This block of code is executed if the expression equals value1
        break;
    case value2:
        // This block of code is executed if the expression equals value2
        break;
    default:
        // This block of code is executed if the expression doesn't match any of the cases
}
