Sharof rashidov nomidagi samarqand davlat universiteti dasturlash asoslari

struct complex alfa = {1.2, -4.5}, betta = {5.6, -7.8), sigma;

sigma.real = alfa.real + betta.real;

sigma.imag = alfa.imag + betta.imag;

Aniq strukturalar elementlari dasturda alohida kiritilishi va chiqarilishi zarur. Quyidagi misolda xizmatchi strukturasi kiritiladi:

• #include
• struct employee
• {
• char name [64];
• long employee_id;
• float salary;
• char phone[10];
• int office_number;
• } worker;

• Strukturalarga murojaat

• void show_employee(employee worker)
• {
• printf("Ismi: %s", worker.name);
• printf("\nTelefon: %s",worker.phone);
• printf("\nNomer: %ld",worker.employee_id);
• printf("\nOylik: %f",worker.salary);
• printf("\nOfis: %d",worker.office_number);
• };
• int main()
• {
• worker.employee_id = 12345;
• worker.salary = 25000.00;
• worker.office_number = 102;
• printf("\n ismi:");
• scanf("%s",&worker.name);
• printf("\n telefon:");
• scanf("%s",&worker.phone);
• show_employee(worker);
• return 0;
• }

• Birlashmalar

• Strukturalarga yaqin tushuncha bu birlashma tushunchasidir. Birlashmalar union xizmatchi so’zi yordamida kiritiladi. Misol uchun:
• union
• {
• long h;
• int i,j;
• char c[4]
• }UNI;
• Birlashmalarning asosiy xususiyati shundaki, uning hamma elementlari bir xil boshlang’ich adresga ega bo’ladi.
• Birlashmalarning asosiy afzalliklaridan biri xotira biror qismi qiymatini har xil tipdagi qiymat shaklida qarash mumkin.

• union
• {
• float f;
• unsigned long k;
• char h[4];
• }fl;
