When I compile this program, it outputs both the corresponding switch case and the default tag contents, the only value it doesn\'t print out for is January, any help would

    You just need an extra case to handle the stray '\n' that comes from you pressing enter at your terminal. January should work if you just type 1

    Edit:Actually I just tested it on Linux and it works flawlessly, there might be some minor differences on Windows, though.

    while (month != EOF)
    {
            switch (month)
            {
    
                case 49:
                month2 = getchar();
    
                switch (month2)
                {
                    case 10:
                        printf("January \n");
                        break;
                    case 48:
                        printf("October \n");
                        break;
                    case 49:
                        printf("November \n");
                        break;
                    case 50:
                        printf("December \n");
                        break;
                }
                break;
    
                    case 50:
                        printf("February \n");
                        break;
                    case 51:
                        printf("March \n");
                        break;
                    case 52:
                        printf("April \n");
                        break;
                    case 53:
                        printf("May \n");
                        break;
                    case 54:
                        printf("June \n");
                        break;
                    case 55:
                        printf("July \n");
                        break;
                    case 56:
                        printf("August \n");
                        break;
                    case 57:
                        printf("Septembe \n");
                        break;
                    // Filter out stray \n
                    case '\n':
                        break;
                    default: printf("Error \n");
    
    
    
    
    
                }
                month = getchar();
    }
    
    
    system("PAUSE");
    return (0);
