    if(month == 1) {
 days = 31;
} else if (month = 2){
 days = 28;
} else if (month = 3){
 days = 31;
} else if (month = 4){
 days = 30;
} else if (month = 5){
 days = 31;
} else if (month = 6){
 days = 30;
} else if (month = 7){
 days = 31;
} else if (month = 8){
 days = 31;
} else if (month = 9){
 days = 30;
} else if (month = 10){
 days = 31;
} else if (month = 11){
 days = 30;
} else if (month = 12){
 days = 31;
}

    Save this data into a table and create this table:

1

[31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]

1

charType = charTypeTable[inputChar];
