Combine numbers in string

hi, can someone help me on the problem that i had:

Problem:

the string output is:4488118417,
and i split it to two: 44 88 11 84 17,
and how can i make 44 in one string, usually 44 is str[0] and str[1].

for example

str[0]=44
str[1]=88
str[2]=11
str[3]=84
str[4]=17

This is the code that i stuck with:

Code:

---

    stringstream numbers;

/* Insert integer into stringstream*/
    numbers <<numLowerCaseLetter(name)<<sumAscii(name)<<lastValue<<counter<<sum;

/* Convert stringstream into string.*/
    string str = numbers.str();

    if(str.size() % 2 == 0)
    {
        for(int i = 0; i < str[i]; i=i+2)
        {
                cout<<str.substr(i,2)<<" "; 
        }
    }   
    else
    {
       
        str.size()+1;
        str.append( 1, '0' );
       
        for(int i = 0; i < str[i]; i=i+2)
        {
            cout<<str.substr(i,2)<<" ";
        }

---

Try This

Code:

---

#include<iostream>
#include<string>
using namespace std;
int main()
{
       
        string str="12345678";
        string array[5];
        int i=0;
        int k=0;
    while(i<str.size()-1)
    {
        array[k]=str.substr(i,2);
                cout<<array[k]<<endl;
                i+=2;
                k+=1;
        }   
        return 0;
}
