सी में एक संरचना में लचीले ऐरे सदस्यों का मतलब है कि हम संरचना के भीतर इसके आयाम के बिना सरणी घोषित कर सकते हैं और इसका आकार प्रकृति में लचीला होगा। लचीला सरणी सदस्य कक्षा का अंतिम सदस्य होना चाहिए।
यहां एक उदाहरण दिया गया है:
उदाहरण
#include

//structure of type employee and must contain at least one more named member
in addition to the flexible array member.
struct employee
{
int emp_id;
int name_len;
int emp_size; //‘emp_size’ variable is used to store the size of flexible
character array emp_name[].
char emp_name[]; //Flexible array member emp_name[] should be the last member of class.
};
struct employee *createEmployee(struct employee *e, int id, char a[])
{
e = (struct employee *)malloc( sizeof(*e) + sizeof(char) * strlen(a)); //memory allocation
e->emp_id = id;
e->name_len = strlen(a);
//Assigning size according to size of emp_name which is a copy of user provided
array a[].
strcpy(e->emp_name, a);
return e;
}
void printEmployee(struct employee *e) //print the details of the employee.
{
printf("Employee_id : %d\n" "Employee Name : %s\n" "Name Length: %d\n\n", e->emp_id, e->emp_name, e->name_len);
}
int main()
{
struct employee *e1 = createEmployee(e1, 26, "Ram");
struct employee *e2 = createEmployee(e2, 53, "Madhu");
printEmployee(e1);
printEmployee(e2);
printf("Size of structure Employee: %lu\n",
sizeof(struct employee));
return 0;
} आउटपुट
Employee_id : 26 Employee Name : Ram Name Length: 3 Employee_id : 53 Employee Name : Madhu Name Length: 5 Size of structure Employee: 12
