Can someone please explain how things are saved in c++? I have made many codes but how do I make a code save data like video games save data so when the user closes out and opens it back up data is saved? Can you use the picture as the example please? also side question: how are codes uploaded into things? I had made codes on computers but I have never actually uploaded a code in anything, like i have made codes that add things but never put it in a caculater, I have made codes for receipts but never put it in a receipt printer.

char numi; char num2; cout cout > numi; if (cin >> nul) bool numestay - true; else if (cin >> num2) bool numistay = false; cout
