int i, j;
for (i = 0; i < 3; i++) {
    for (j = 0; j < 2; j++) {
        printf("%d%d", i, j);
    }
}

000112001122

001012011202

Explanation

Let's break down the given code snippet:

int i, j;
for (i = 0; i < 3; i++) {
    for (j = 0; j < 2; j++) {
        printf("%d%d", i, j);
    }
}

Outer loop (over i): Runs 3 times (from i = 0 to i = 2).
Inner loop (over j): Runs 2 times for each iteration of i (from j = 0 to j = 1).
The printf prints the values of i and j in the format i j without spaces.

Let's go through the iterations:

When i = 0, j will take values 0 and 1, so the output will be 00 and 01.
When i = 1, j will take values 0 and 1, so the output will be 10 and 11.
When i = 2, j will take values 0 and 1, so the output will be 20 and 21.
