error banksimulaion

Hej!

Jag får upp  error : expected initializer before 'account' och expected unqualified -id before '{' token .

Vad gör jag för fel?

#include <iostream>

using namespace std;

int main()

{

int deposit;
int target;
float intrest;
float account;
int monthcount;
int yearcount=1;

void count()

account+=deposit;
while(account<target)
{
float temp=intrest/100+1;
account=account*temp;
monthcount++;
if(monthcount==12)
{
account+=deposit;
if(account>=target)
{break;}
yearcount++;
monthcount=0;

}
}
cout<<"calculated time until target"<<endl<<endl;
cout<<"years:"<<yearcount<<endl
<<"month:"<<monthcount<<endl
<<"account:"<<float(account)<<endl;

}

{

cout<<"deposit per year?"<<endl;
cin>>deposit;
cout<<"target for account?"<<endl;
cin>>target;
cout<<"intrest per month?%"<<endl;
cin>>intrest;

cout<<endl;
count();
cout<<endl;
system("pause");
return;
}
