Nested Loops

You can also place one loop inside another loop, known as a nested loop.

The “inner loop” executes once for every iteration of the “outer loop.”

Example

int i, j;

// Outer loop
for (i = 1; i <= 2; ++i) {
printf(“Outer: %d\n”, i); // Executes 2 times

// Inner loop
for (j = 1; j <= 3; ++j) {
printf(” Inner: %d\n”, j); // Executes 6 times (2 * 3)
}
}
