#include <stdio.h>
struct employee {
	int id;
	int age;
	double salary;
};




int main(void)
{


	int option = 0, i = 0, j = 0, n = 0, flag = 0;
	
	struct employee emp[SIZE] = {{0}};




	printf("---=== EMPLOYEE DATA ===---\n\n");


	do {
		printf("\n");
		printf("1. Display Employee Information\n");
		printf("2. Add Employee\n");
		printf("3. Update Employee Salary\n");
		printf("4. Remove Employee\n");
		printf("0. Exit\n\n");
		printf("Please select from the above options: ");


		scanf("%d", &option);
		printf("\n");


		switch (option) {
		case 0:
			printf("Exiting Employee Data Program. Good Bye!!!\n");
			printf("\n");


			break;
		case 1:


			
			printf("EMP ID  EMP AGE EMP SALARY\n");
			printf("======  ======= ==========\n");
			for (i = 0; i < SIZE; i++) {


				if (emp[i].id > 0) {
					printf("%6d%9d%11.2lf", emp[i].id, emp[i].age, emp[i].salary);
					printf("\n");
					
				}
				
			}
			break;
		case 2:	




			printf("Adding Employee\n");
			printf("===============\n");


			if (n < SIZE){
			printf("Enter Employee ID: ");
			scanf("%d", &emp[n].id);
			printf("Enter Employee Age: ");
			scanf("%d", &emp[n].age);
			printf("Enter Employee Salary: ");
			scanf("%lf", &emp[n].salary);
			n++;
			
		} else 
				printf("ERROR!!! Maximum Number of Employees Reached\n");
			


			break;




		case 3:
			printf("Update Employee Salary\n");
			printf("===============\n");
			do {
				printf("Enter Employee ID: ");
				scanf(" %d", &j);


				for (i = 0; i < SIZE; i++) {


					if (j == emp[i].id) {


						printf("The current salary is $%0.2lf", emp[i].salary);
						printf("\nEnter New Employee Salary:");
						scanf(" %11lf", &emp[i].salary);
						flag = 1;
					} 






					if (j != emp[i].id) {
							printf("*** ERROR: Employee ID not found! ***");
							printf("\n");


					}


					
				}
			
				
			} while (flag == 0);
			
			
			break;


		case 4:
			


			break;
		default:
			printf("ERROR: Incorrect Option: Try Again\n");
		}


	} while (option != 0);




	return 0;
}

Any help will be appreciated/

Hi, In case 3, when I type the wrong ID i get the error messaged printed 4 times, when I get is right it prints depending on the position of the value thats stored in the array.

I'd recommend you try to figure out why when you enter a "correct" ID it prints the error message multiple times. If you fix this it may just fix the other problem. Hint: What is that for() loop doing?

Thanks, Got the printf issue done. Now my instructions were to copy the do-while for case 4, after the first incorrect it will just end and bring up the menu. If I do case 4 then case 3, Case 3 will have this issue.

		case 3:
			printf("Update Employee Salary\n");
			printf("===============\n");
			do {
				printf("Enter Employee ID: ");
				scanf(" %d", &j);


				
				for (i = 0; i < SIZE; i++) {
					if (j == emp[i].id)
					{


						printf("The current salary is %0.2lf", emp[i].salary);
						printf("\nEnter New Employee Salary: ");
						scanf(" %11lf", &emp[i].salary);
						flag = 1;
						break;


					}
				}








					if (j != emp[i].id) {
						printf("*** ERROR: Employee ID not found! ***");
						printf("\n");
						


					}
			} while (flag == 0);


			
			
			break;


		case 4:
			printf("Remove Employee\n");
			printf("===============\n");
			do {
				printf("Enter Employee ID: ");
				scanf(" %d", &j);




				for (i = 0; i < SIZE; i++) {
					if (j == emp[i].id)
					{
						printf("Employee %d will be removed\n", emp[i].id);
						emp[i].id = 0;
						flag = 1;
						break;	
					}
					
				}
					
					if (j != emp[i].id) {
						printf("*** ERROR: Employee ID not found! ***");
						printf("\n");
					}
			} while (flag == 0);


			
			break;




		default:
			printf("ERROR: Incorrect Option: Try Again\n");
		}


	} while (option != 0);




	return 0;
