  1. POchanging datas inside switch(), accumulation
    text
    copied!<p>Im doing a project that stimulate the ATM in C++ and having some troubles with the accumulators, my question is: I am use switch (here is case 1) to change the values of 2 variables which are declared inside the function that contains the switch(), however the values only change inside case 1 and they reset themselves to the original value (like const declaration), so when I try to print the checking and saving (in case 3 and 4) it prints out the original amount (1000). So I dont know what I did wrong here. Problem is not with the amount, I have tried replacing amount with a numeric value but still doesnt work. Please help</p> <pre><code>int transactions() { double checking = 1000.00, saving = 1000.00; double amount; switch (inputRange(menu())) { case 1: system("cls"); amount = getAmount("Enter an amount to transfer from checking to saving: "); checking -= amount; saving += amount; cout &lt;&lt; checking &lt;&lt; " " &lt;&lt; saving; // they only change inside case 1 cout &lt;&lt; "\nTransaction completed! \n\nPress ENTER to return to main menu..."; cin.ignore(99,'\n'); break; </code></pre> <p>updates*** I already got it guys, thanks, just forgot about the &amp;, this works</p> <pre><code> int transactions(double &amp;checkBal, double &amp;saveBal) { double amount; //set precision cout &lt;&lt; fixed &lt;&lt; showpoint &lt;&lt; setprecision(2); switch (inputRange(menu())) { case 1: system("cls"); checkingToSaving (getAmount("Enter an amount to transfer from checking to saving: "), checkBal, saveBal); cout &lt;&lt; "\nTransaction completed! \n\nPress ENTER to return to main menu..."; cin.ignore(99,'\n'); break; </code></pre>
