1. What are Loops?

• Loops let you repeat code multiple times.
• They run while a condition is true (or for a fixed number of times).

2. for Loop

• Best when you know how many times you want to repeat.

for (init; condition; update) {
    // code
}

Example:

for (int i = 0; i < 5; i++) {
    cout << i << " ";
} /* Output in this case: 0 1 2 3 4 */

3. while Loop

• Repeats as long as condition is true.
• Condition is checked before each iteration.

while (condition) {
    // code
}

4. do-while Loop

• Similar to while, but condition is checked after the loop.
• Guarantees at least one execution.

do {
    // code
} while (condition);
