Question

Can you tell me what's wrong with this code? The compiler keeps saying [Error] too few arguments to function 'float calcNewBal(float, float)'

Answer 1

#include <stdio.h>
#include <conio.h>

float calcNewBal(float, float);
float calcRunningBal(float, float);
float calcTaxDue(float, float);
float calcEomBal(float, float);

int main()
{
float newBal, runningBal, taxDue, eomBal;

newBal = calcNewBal(newBal);
runningBal = calcRunningBal(runningBal);
taxDue = calcTaxDue(taxDue);
eomBal = calcEomBal(eomBal);

return 0;
}/*End main function*/


/*Function to calculate new balance*/

float calcNewBal(float startingBal, float totWithdrawl)
{
/*Local variable declaration*/
float newBal;

printf("Enter customer's starting balance and total withdrawls ");
scanf("%f%f", &startingBal, &totWithdrawl);

newBal = startingBal - totWithdrawl;

return newBal;
}/*End function to calculate new balance*/



/*Function to calculate running balance*/

float calcRunningBal(float newBal, float totDeposit)
{
/*Local varibale declaration*/
float runningBal;

printf("Enter customer's new balance and total deposit: ");
scanf("%f%f", &newBal, &totDeposit);

runningBal = newBal + totDeposit;

return runningBal;
}/*End function to calculate running balance*/



/*Function to calculate tax due*/

float calcTaxDue(float totDeposit, float totWithdrawl)
{
/*Local variable declaration*/
float taxDue;

printf("Enter customer's total withdrawl and total deposit:");
scanf("%f%f", &totDeposit, &totWithdrawl);

taxDue = (totDeposit + totWithdrawl) * 0.1;

return taxDue;

}/*End function to calculate tax due*/



/*Function to calculate end of month balance*/

float calcEomBal(float runningBal, float taxDue)
{
/*Local variable declaration*/
float eomBal;

printf("Enter customer's running balance and tax due: ");
scanf("%f%f", &runningBal, &taxDue);

eomBal = runningBal - taxDue;

return eomBal;

}/*End function to calculate end of month balance*/

Answer 2

`float calcNewBal(float, float);` says there are two args

`newBal = calcNewBal(newBal);` only one given in call

Answer 3

So then how should I correct this?

Answer 4

Need to put `calcNewBal(newBal, variable);` where `variable` is whatever `totWithdrawal` is supposed to be. Did you write this code?

Answer 5

Thank you! Yes I did write this code.
