How do I fix this program to actually display what it needs to display. It's a C$++$ program and I don't know why it doesn't work.

#include

using namespace std;

$//$declarations

void checkBalance$($float balance$)$;

float depositMoney$($float balance$)$;

float withdrawMoney$($float balance$)$;

$\{$

float balance $=0\mathrm{.}0$;

cout $<<$ "Welcome to the Simple ATM System!

do $\{$

cout $<<"$
