Not sure how to write the last of this source code.

[zmlink]

this is what i have thus far and to no avail i have yet to figure out how to write the last bit of this algorithm included after my source code any help is good help at this point i think im just making it worse the more i try im sure its something easyer then what im trying to do..

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
   int amount, newAmount, intevpludrestRate;
   
   cout <<"Please enter the dollar amount."<<endl;

cin>> amount; 
             
    cout <<"Please enter the interest rate(e.g., nine percet should be entered as 9.0). "<<endl;

cin>> interestRate;                            
                    
return 0;
}

algorithm i have to work with.
// Start
// Declarations
// num amount
// num newAmount
// num interestRate
// output "Please enter the dollar amount. "
// input amount
// output "Please enter the interest rate(e.g., nine percet should be entered as 9.0). "
// input interestRate
// newAmount = FutureValue(amount,interestRate)
// output "The new dollar amount is ", newAmount
// Stop
//
//
//
// num FutureValue(num initialAmount, num interestRate)
// Declarations
// num finalAmount
// finalAmount = (1 + interestRate/100) * initialAmount
// return finalAmount
i think i have everything ok but beyond the point i stopped at i am lost what i have is error free at least ;/

 newAmount = ( amount, interestRate); { 
             cout <<"The new dollar amount is ", newAmount"<<endl; cin>>;               
              }                     
                    
return 0;
} 

says missing character not a clue what that means is this close to that example.

Your function call does not have the name of the function that you want to call.

[giblit]

it means int newAmount if you are going to return 0 which is unnecessary
just make it void and newAmount and after that you have a bunch of problems on line 2
for 1) you should have << where the comma is.
2) remove the " after newAmount.
and 3) why do you have a cin?
and 4) you should probably update the new dollar amount before printing
eg:

 amount *= (interestrate/100);
std::cout << "The new amount is: " <<  amount << std::endl;

hmm so i removed the " i dont see the << your talking about and removed the cin>> not sure i thought it was needed on a cout stament and the return 0 i just used so i can compile it for errors and run it so i know what im doing works for the moment..

 newAmount = ( amount, interestRate); { 
             cout <<"The new dollar amount is ", newAmount<<endl;                
              }                     
                    
return 0; 
  lol
}

[/code]

oh i needed <<

[zmlink]

are you saying the updated new dollar amount should go before do i put it before the other function

this is what i understood .

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
   int amount, newAmount, interestRate;
   
   cout <<"Please enter the dollar amount."<<endl;

cin>> amount; 
             
    cout <<"Please enter the interest rate(e.g., nine percet should be entered as 9.0). "<<endl;

cin>> interestRate;   
newAmount = ( amount, interestRate); {  amount *= (interestRate/100);
std::cout << "The new amount is: " <<  amount << std::endl;
             cout <<"The new dollar amount is "<< newAmount<<endl;                
             
              }                     
                    

return 0;
}

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
   int amount, newAmount, interestRate;
   
   cout <<"Please enter the dollar amount."<<endl;

cin>> amount; 
             
    cout <<"Please enter the interest rate(e.g., nine percet should be entered as 9.0). "<<endl;

cin>> interestRate;   
newAmount = ( amount, interestRate); {  amount *= (interestRate/100);
std::cout << "The new amount is: " <<  amount << std::endl;
             cout <<"The new dollar amount is "<< newAmount<<endl;                
             
              }                     
                    

return 0;
}

// i know this is incomplete i do not know what i am to do next i have some idea just do not know how to make the function properly i guess . can some one help me figure this out the algorithm is below

alogrithm:
// Start
// Declarations
// num amount
// num newAmount
// num interestRate
// output "Please enter the dollar amount. "
// input amount
// output "Please enter the interest rate(e.g., nine percet should be entered as 9.0). "
// input interestRate
// newAmount = FutureValue(amount,interestRate)
// output "The new dollar amount is ", newAmount
// Stop
//
//
//
// num FutureValue(num initialAmount, num interestRate)
// Declarations
// num finalAmount
// finalAmount = (1 + interestRate/100) * initialAmount
// return finalAmount

[keskiverto]

I did point you to tutorials. Their first example has function "addition". Your instructions require function "FutureValue".

[giblit]

By the way you are trying create a function inside your main function
there are 2 options

int newAmount(int a, int b)
{
//do stuff
}
int main()
{
amount = newAmount(amount, interestRate);
}

or

int main()
{
newAmount = amount *= (interestRate / 100);
std::cout << newAmount << std::endl;
}
