Else-If Ladder

In C, the else-if ladder is used when you need to check multiple conditions one after another. It is a more structured way to handle multiple options instead of using many separate if statements.

Syntax:

if (condition1) {
    // code runs if condition1 is true
} else if (condition2) {
    // code runs if condition2 is true
} else if (condition3) {
    // code runs if condition3 is true
} else {
    // code runs if none of the above conditions are true
}

Example:

#include <stdio.h>

int main() {
    int marks = 68;

    if (marks >= 90) {
        printf("Grade A\n");
    } else if (marks >= 75) {
        printf("Grade B\n");
    } else if (marks >= 60) {
        printf("Grade C\n");
    } else if (marks >= 40) {
        printf("Grade D\n");
    } else {
        printf("Fail\n");
    }

    return 0;
}

In this program, the value of marks is checked against several ranges. Only the first true condition's block will run.

How it Works:

The program checks conditions from top to bottom.
As soon as it finds a true condition, it runs that block and skips the rest.
If no condition is true, the else block (if present) will run.

Summary

The else-if ladder is useful when you have multiple possible conditions and only one should be executed. It helps keep your code organized and easy to read. 🔁
