for Loops

The Classic for Loop

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

Three parts: init ; condition ; update

Count down

for (int i = 10; i >= 1; i--) {
    cout << i << " ";
}
// 10 9 8 7 ... 1

Nested loops

for (int i = 1; i <= 3; i++)
    for (int j = 1; j <= 3; j++)
        cout << i * j << "\t";

Your Task

Write power(int base, int exp) that returns base raised to exp using a for loop (no pow()).
Example: power(2, 10) → 1024
