Conditional Statement

 

      Conditional Statements in C Language

Conditional statements are used to perform different actions based on whether a condition is true or false. They help control the flow of a program.

---

🔹 1. if Statement

Executes a block of code only if the condition is true.

if (a > b) {
    printf("A is greater than B");
}

---

🔹 2. if-else Statement

Executes one block if the condition is true, another if false.

if (a > b) {
    printf("A is greater");
} else {
    printf("B is greater or equal");
}

---

🔹 3. else-if Ladder

Checks multiple conditions sequentially.

if (a > b) {
    printf("A is greater");
} else if (a < b) {
    printf("B is greater");
} else {
    printf("A and B are equal");
}

---

🔹 4. Nested if

An if statement inside another if.

if (a > 0) {
    if (a < 100) {
        printf("A is between 1 and 99");
    }
}

🔹 5. switch Statement

Used to test a variable against multiple constant values.

int choice = 2;
switch (choice) {
    case 1:
        printf("Choice is 1");
        break;
    case 2:
        printf("Choice is 2");
        break;
    default:
        printf("Invalid choice");
}
