Помогите пожалуйста написать программу на языке С, не используя string, заранее спасибо

*começa a digitar o código em C, seguindo as especificações*

```c
#include <stdio.h>
#include <stdlib.h>

typedef struct {
char surname[32];
char name[32];
int yearOfBirth;

for (int i = 0; i < count; i++) {
if (strcmp(employees[i].surname, targetSurname) == 0) {
return employees[i];
}
}
Employee empty;
strcpy(empty.surname, ""); // dummy employee
return empty;
}

void correctEmployee(Employee* emp, char newSurname, int newYOB, char newEducation) {
strcpy(emp->surname, newSurname);

emp.yearOfBirth = 1990;
strcpy(emp.education, "higher");
fwrite(&emp, sizeof(Employee), 1, fp);
