Answer:
void print2(int row) {
for (int i = 0; i < row; i++) {
char ch = 'a';
char print = ch;
for (int j = 0; j <= i; j++) {
cout << print++;
}
cout << endl;
}
}
int count_digits(int num) {
int count = 0;
int temp = num;
while (temp != 0) {
temp = temp / 10;
count++;
}
return (num % count);
}

Answer:
Serial SCSI
Explanation:
Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.
Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.
