Please explain each step in detail for this particular code. I would greatly appreciate what each line does! This is in C++

#include

using namespace std;

int main() { int arr[]={50, 120, 130, 150, 190, 200, 215, 300, 318, 430, 560, 600, 150, 660, 700, 150, 800, 760, 730, 589}; int commission; int total; while(1) { cout<<"Enter commision value(-1 to quit): "; cin>>commission; if(commission==-1) { break; } total=0; for(int i=0;i<20;i++) { if(arr[i]==commission) { total++; } } cout<

return 0; }
