C 结构中的灵活数组成员意味着我们可以在结构中声明没有维度的数组,并且其大小本质上是灵活的。灵活数组成员必须是类的最后一个成员。
下面是一个示例:
示例
#include#include#include//structure of type employee and must contain at least one more named memberin 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" "Employee Name : %s
" "Name Length: %d

", 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
", sizeof(struct employee)); return 0;}
输出
Employee_id : 26Employee Name : RamName Length: 3Employee_id : 53Employee Name : MadhuName Length: 5Size of structure Employee: 12
