We have given an array of string and we have to serialize the array of string and deserialize the serialized string. 

Examples:

Input :  "geeks", "are", "awesome"
Output : Serialized String : 5~geeks3~are7~awesome
         Deserialized String : geeks are awesome

Input :  "hello", "guys", "whats", "up!!!"
Output : Serialized String : 5~hello4~guys5~whats5~up!!!
         Deserialized String : hello guys whats up!!!

Serialization : Scan each element in a string, calculate its length and append it with a string and a element separator or deliminator (that deliminator should not be present in the string). We append the length of the string so that we know the length of each element. 

Deserialized Function : Find the position of the deliminator, then from the position + 1 to length of word we store it in an array as a single element. 

Implementation:

C++

// CPP program to serialize and
// deserialize the array of string
 
#include <iostream>
 
using namespace std;
 
// Function to serialized the array of string
string serialize(string str[], int ln)
{
    string temp = "";
    for (int i = 0; i < ln; i++) {
        int ln = str[i].length();
        temp.push_back('0' + ln);
        temp = temp + "~" + str[i];
    }
    return temp;
}
 
// Function to deserialize the string
void deserialized(string str, string deserialize[], int ln)
{
    int len, pos = 0;
    string temp = "";
    int i = 0;
    while (pos > -1) {
        pos = str.find("~", pos + 1);
        if (pos > 0) {
            len = str[pos - 1] - 48;
            temp.append(str, pos + 1, len);
            deserialize[i++] = temp;
            temp = "";
        }
    }
}
 
// Driver function
int main()
{
    string str[] = { "geeks", "are", "awesome" };
 
    int ln = sizeof(str) / sizeof(str[0]);
    string serializedstr = serialize(str, ln);
 
    cout << "Serialized String : " << serializedstr << endl;
 
    string deserialize[ln];
    deserialized(serializedstr, deserialize, ln);
 
    cout << "Deserialized String : ";
    for (int i = 0; i < ln; i++)
        cout << deserialize[i] << " ";
 
    return 0;
}
