C Nested if-else Statements 🚀

Welcome to our deep dive into C Programming! Today, we'll be exploring the intricacies of the Nested if-else statements. Let's get started!

Understanding if-else Statements 💡

Before we dive into nesting, let's quickly review the basic if-else statement. It's a control structure that allows us to perform different actions based on a condition.

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

Nesting if-else Statements 📝

Now, let's take it a step further and nest if-else statements. This means we can have an if-else statement inside another if-else statement. This allows us to create more complex decision-making structures in our code.

if (condition1) {
    // Code to execute if condition1 is true
} else if (condition2) {
    // Code to execute if condition1 is false and condition2 is true
} else {
    // Code to execute if neither condition1 nor condition2 is true
}

In the above example, condition1 is tested first. If it's true, the code within the first if block is executed, and the remaining else if and else blocks are skipped. If condition1 is false, then condition2 is tested. If condition2 is true, the code within the else if block is executed. If both condition1 and condition2 are false, the code within the else block is executed.

Practical Example 🎯

Let's consider a practical example of nested if-else statements. We'll write a program to find the grade of a student based on their marks.

#include <stdio.h>

int main() {
    int marks;
    printf("Enter your marks: ");
    scanf("%d", &marks);

    if (marks >= 90) {
        printf("Grade: A\n");
    } else if (marks >= 80) {
        printf("Grade: B\n");
    } else if (marks >= 70) {
        printf("Grade: C\n");
    } else if (marks >= 60) {
        printf("Grade: D\n");
    } else {
        printf("Grade: F\n");
    }

    return 0;
}

In this example, we're asking the user to enter their marks. Depending on the marks, we're printing the corresponding grade. If the marks are 90 or above, we print 'Grade: A'. If the marks are between 80 and 89, we print 'Grade: B', and so on.

Nested if-else with Multiple Conditions 💡

You can also nest if-else statements with multiple conditions. This allows you to create more complex decision structures.

if (condition1) {
    if (condition2) {
        // Code to execute if both condition1 and condition2 are true
    } else {
        // Code to execute if condition1 is true but condition2 is false
    }
} else {
    // Code to execute if condition1 is false
}

Note: In C, the types for if-else are if (boolean_expression), else if (boolean_expression), and else. Make sure to use the correct syntax when writing your code.
