Thread: Example

Does anybody have an example of code for a mortgage calculator which prints out a table showing balance outstanding each week with total interest paid until the capital is fully repaid,when amount borrowed, interest rate and monthly payment are entered?
Thanks in advance.

post your ideas for one

my ideas are above.

Of course be sure to do some error checking to make sure you don't make an infinite loop if for example the monthly repayments are not large enough, and the debt grows larger and larger....

I have made a start on the code, will this work, are there any errors, i am a complete newbie to programming as you can probably tell! Any input would be much appreciated.
Thanks.

Code:

# include <stdio.h>
# include <math.h>
# include <string.h>
# include <stdlib.h>

void main ()

{
	float capital,rate,payment,week,int,debt,tint,year,newweek;

	printf(“Please enter amount borrowed (£)\n\r”);
	scanf(“%f,&capital);
	printf(“Please enter interest rate(%)\n\r”);
	scanf(“%f,&rate);
	printf(“Please enter monthly payment (£)\n\r”);
	scanf(“%f,&payment);

printf(“Year\t Week\t Balance Outstanding\t Total Interest\n\r”);

		week=1
		int=(rate/364*7/100)*capital
		debt=capital+(int*capital*week)
		tint=int*week
		year=week/12+1%.0

printf(“%f,\t, %f,\t, %f,\t, %f,\t”,year,week,debt,tint);

		newweek=week++
		int=(rate/364*7/100)*capital
		debt=capital+(int*capital*week)
		tint=int*week
		year=week/12+1%.0

printf(“%f,\t, %f,\t, %f,\t, %f,\t”,year,week,debt,tint);

while (debt>0)
	{
newweek=newweek++
		int=(rate/364*7/100)*capital
		debt=capital+(int*capital*week)
		tint=int*week
		year=week/12+1%.0

printf(“%f,\t, %f,\t, %f,\t, %f,\t”,year,week,debt,tint);
}

well first u can't use keywords for variable identifiers, so u wouldn't beable to use int as a float variable.

int is the keyword for declaring an integer variable.

it seems that u've missed the closing quotations for all your scanf function calls

[code]
scanf(“%f,&capital);

// should be like
scanf("%f", &capital);
[code]

atm thats call i can see.

So just add the closing quotation marks and change the name of the 'int' variable to something else.

main returns int, always, think about it, it makes perfect sense.
