Here are the main functions of an operating system:
1) Manage the resources of the device
The operating system controls how much of each resource is distributed, and it controls things like the processing unit and memory.
2) Establish a interface for the user of the device
The operating system must classify what the classes of the script/code have to do and what they implement.
3) Service application software
The operating system must service each application that is downloaded onto the device. It must balance it's use of storage between apps.

int main(){
char str[20];
int i=0;
printf("Enter a name: ");
gets(str);
printf("%c",*str);
while(str[i]!='\0'){
if(str[i]==' '){
i++;
printf("%c",*(str+i));
}
i++;
}
return 0;
}

Answer:
public class Date {
private int month;
private int day;
private int year;
// Constructor
public Date(int month, int day, int year) {
this.month = month;
this.day = day;
this.year = year;
}
//Getters and setter
public int getMonth() {
return month;
}
public void setMonth(int month) {
this.month = month;
}
public int getDay() {
return day;
}
public void setDay(int day) {
this.day = day;
}
public int getYear() {
return year;
}
public void setYear(int year) {
this.year = year;
}
void displayDate(){
System.out.println(getMonth()+"/"+getDay()+"/"+getYear());
}
}
//Test Class
class DateTest {
public static void main(String[] args) {
Date dateOne = new Date(12, 25, 2019);
dateOne.displayDate();
}
}
Explanation:
- Using Java programming Language
- Create the Date class with the instance variables (Month, day and year) all of type int
- Create the the constructor to initialize all the instance variables
- Create getters and setters for all the instance variables
- Create the displayDate() method which uses string concatenation along with the get() method of all the instance variables
- Create a test class that initializes an instance of the of the Date class
- Call the method displayDate on the instance of the class created
