I. Bob Dasturlash amaliyoti algoritm va dasturlarni ishlab chiqish

Strukturalarga murojaat
Aniq strukturalar ta’riflanganda massivlar kabi inisializasiya qilinishi mumkin.
Masalan
struct complex sigma = {1.3; 12.6};
struct tovar coats = {"pidjak", 40000, 7.5, 220, "12.01.97");
Bir xil tipdagi strukturalarga qiymat berish amalini qo’llash mumkin:
struct complex alfa; alfa = sigma;
Lekin strukturalar uchun solishtirish amallari aniqlanmagan. Strukturalar elementlariga quyidagicha murojaat qilish mumkin:
Struktura_nomi.element_nomi.
'Nuqta amali' struktura elementiga murojaat qilish amali deyiladi. Bu amal qavs amallari bilan birga eng yuqori ustivorlikka ega.
Strukturalarga murojaat
Misol:
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;
}

Nomsiz struktura
Nomsiz tuzilma , umumiy ko’rinish
Struct
{ elenentlarni aniqlash }
< tuzilmalar ro’yxati > ;
Masalan , EHM коnfirasiyasi :
• Protsessori tipi (char [10]) ;
• МГц dagi ishchi chastota (int ) ;
• М Б lardagi asosiy xotira (int ) ;
• МБ lardagi qattiq disk hajmi (int )
Struct
{
char processor [10 ] ;
int frequency ;
int memory ;
int disk ;
