How can I reduce the amount of memory that my program takes up after compilation?

Question

#include <iostream>
#include<string>
using namespace std;

void printpatt(string a, int i);

int main()
{
int i = 0;
string a = "";
while (getline(cin, a))
{
printpatt(a, i);
i = 0;
}
return 0;
}

void printpatt(string a, int i)
{
string temp = "";
while (a[i] != '\0')
{
if (a[i] == 'a' && a[i + 1] == 'b' && (a[i + 2] == 'b' || a[i + 2] == 'c'))
{
temp += a[i];
temp += a[i + 1];
i += 2;
}
else if (a[i] == 'b' && a[i - 1] == 'b' && a[i - 2] != 'c' && (a[i - 2] == 'a' || a[i - 2] == 'b') && (a[i + 1] == 'b' || a[i + 1] == 'c'))
{
temp += a[i];
i++;
}
else if (a[i] == 'c' && a[i - 1] == 'b' && (a[i - 2] == 'a' || a[i - 2] == 'b') && a[i - 3] != 'c')
{
temp += a[i];
if (temp.length() > 2 && temp[0] == 'a' && temp[temp.length() - 1] == 'c')
{
cout << temp << endl;
temp = "";
i++;
}
}
else {
temp = "";
i++;
}
}
}

You could use 'Memory' and to delete 'delete[] memory' but you can find more help right here https://stackoverflow.com/questions/15837535/how-to-clear-the-dynamically-allocated-memory-which-is-in-heap
