    	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++) {

    			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.

    Code:
    		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;
    }
