For each of the following C++-like pseudo code segments, write equivalent ARM assembly language instructions.

1. for (r4 = 0; r4 < 100; r4++) {

r1 = r1 + r4;

r2 = r2 - 1;

}

2. while (r4 <= r5) {

r1 = r1 - 2;

r2 = 40 - r2;

r4 = r4 + 1;

}

3. do {

r1 = r1 - 2;

r2 = 40 r2;

r4 = r4 + 1;

} while (r4 < r5)
