Hayotiy misollar

Hayotiy misollar

Misollarimizda ko‘pincha o‘zgaruvchi nomlarini ularning ma’lumot tipiga moslab soddalashtiramiz (int tiplari uchun myInt yoki myNum, char tiplari uchun myChar va hokazo). Bu chalkashlikning oldini olish uchun qilinadi.

Biroq o‘zgaruvchilardan foydalanishning amaliy misoli sifatida kollej talabasi haqidagi turli ma’lumotlarni saqlaydigan dastur tuzdik:

// Student data
String studentName = "John Doe";
int studentID = 15;
int studentAge = 23;
float studentFee = 75.25f;
char studentGrade = 'B';

// Print variables
System.out.println("Student name: " + studentName);
System.out.println("Student id: " + studentID);
System.out.println("Student age: " + studentAge);
System.out.println("Student fee: " + studentFee);
System.out.println("Student grade: " + studentGrade);

To‘g‘ri to‘rtburchak yuzini hisoblash

Ushbu hayotiy misolda to‘g‘ri to‘rtburchak yuzini (uzunligi va enini ko‘paytirib) hisoblaydigan dastur tuzamiz:

// Create integer variables
int length = 4;
int width = 6;
int area;

// Calculate the area of a rectangle
area = length * width;

// Print variables
System.out.println("Length is: " + length);
System.out.println("Width is: " + width);
System.out.println("Area of the rectangle is: " + area);
