I wrote a code to manage a coffee machine,
I have a function findC that finds the cheapest capsule in the capsule array
a different function of mine findVP that is supposed to use the findC function's output as variables. however, when I pass the variables mp, ind = findC(prices_copy, quantities_copy, SIZE);
and print them it passes them as 0;
but the 2nd cout : cout << findC(prices_copy, quantities_copy, SIZE); prints the correct output.
why is this ? and how can I pass the output of the function to another
