Почему этот цикл, который ищет сотрудника, не находит его?

Question

Я недавно начал изучать C, и я должен завершить эту программу сотрудника C: https://pastebin.com/b5SyYQQ4

В случае 4 мне нужно сказать * ОШИБКА: идентификатор сотрудника ненайденный!* когда идентификатор не найден, как в случае 3, но, что бы я ни пытался, я потерплю неудачу.

Я очень ценю помощь!

пробовал так же, как в случае 3, но это не удалось.

case 4:
            printf("Remove Employee\n");
            printf("===============\n");
                printf("Enter Employee ID: ");
                scanf("%d", &empId);
                l = 0;
                empFound = 0;
                while (empFound == 0) {
                    l++;
                    if (empId == emp[l].id) {
                        printf("Employee %d will be removed\n\n", empId);
                        empFound = 1;
                    }
                    if (empFound == 0) {
                        printf("*** ERROR: Employee ID not found! ***\n");
                    }
                }
                for (l = l; l < 4; l++) {
                    emp[l].id = emp[l + 1].id;
                    emp[l].age = emp[l + 1].age;
                    emp[l].salary = emp[l + 1].salary;
                }
                i--;
                break;

Я ожидаю:

Remove Employee

===============

Enter Employee ID: 1

*** ERROR: Employee ID not found! ***

Enter Employee ID: 2

Employee 2 will be removed.

Но я получил:

Remove Employee

===============

Enter Employee ID: 1

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

*** ERROR: Employee ID not found! ***

Employee 1 will be removed
