Trying to make a change calculator.

When running and building the task (VScode), I’m getting an error that it is expecting an initializer before “-=”. Not exactly sure where or why that is being expected.

This is the code right now.

#include <iostream>

using namespace std;

int main() {

    const int dollar {100}, quarter {25} , dime {10} , nickel {5}, penny {1};

cout << "Hello, please enter your amount in cents: ";

    int customer {0};
cin >> customer;

cout << "Thank you, you entered: " << customer << " cents." << endl;


int dollarChange {customer / dollar};
    int total_1 {0} = customer - (dollarChange * dollar);

int quarterChange {total_1 / quarter};
   int total_2 {0} -= (quarterChange * quarter);

int dimeChange {total_2 / dime};
    int total_3 {0} -= (dimeChange * dime); 

    
int nickelChange {total_3 / nickel};
    int total_4 {0} -= (nickelChange * nickel);

int pennyChange {total_4 / penny};

cout << "Your change is: " << endl;
cout << "nQuarters: " << quarterChange << endl;
cout << "Dimes: " << dimeChange << endl;
cout << "Nickels: " << nickelChange << endl;
cout << "Pennies: " <<pennyChange << endl;



    return 0;
}

The error message appearing after building the task:

C:ProjectsSection 8main.cpp:41:20: error: expected ',' or ';' before '-=' token
