Please Suggest me the visualforce and controller code to complete my task.I am new to salesforce and unable to proceed with coding using VF and apex code.

So what you have to do is create custom controller, create VF page with custom controller. You have to create those objects in controller constructor, then display in page required fields. Last thing is creating custom save button calling save action from controller

Class CustomController{

public Contact contact {get; set;}
public Reservation__c reservation {get; set;}

public void CustomController(){
    contact = new Contact();
    reservation = new Reservation();
}

public void save(){
    try{
        /** fill in contact required fields other than those in the page **/
        insert contact;

        /** fill in reservation required fields other than those in the page **/
        reservation.Customer_Name__c = contact.Id; // Fill in Cintact lookup
        insert reservation
    }
    catch(Exception e){
        /** Handle exception **/
    }
}

public PageReference cancel(){
    return new PageReference(/** Some Page reference **/);
}

Bit of page

<apex:page Controller="CustomController" >
 <apex:sectionHeader title="Title" subtitle="Some Subtitle"/>
    <apex:form >
        <apex:pageMessages />
        <apex:pageBlock title="Title">
        <apex:pageBlockButtons >
            <apex:commandButton action="{!save}" value="Save"/>
            <apex:commandButton action="{!cancel}" value="Cancel"/>
        </apex:pageBlockButtons>
        <apex:pageBlockSection >

            <apex:inputField value="{!contact.Name}" required="true"/>
            /** use apex:inputField to display all fields you wanted  **/
        </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>
