How to get the Sum

[Angelusmorts]

So i am struggling for days to get this done and all i need is to get the sum of the areas and get them printed on the screen my code is this:

#include<stdio.h>
#include <stdlib.h>
#include<conio.h>  //Not needed in Dev C++//
#define PI 3.1415 
float Area_of_Rectangular(float  length,float width);
float Area_of_Circle(float radius);
int main()
{

Sorry if it's too messed up just made it like this to help me make the chains with every if i made.Feel free to give me a better view of it also

Pass a pointer to aor to the function Area_of_Rectangular() and a pointer to aoc to Area_of_Circle() and print whatever the functions return?

[Angelusmorts]

Sorry but i didn't get that(beginner material) How can i pass a pointer to the functions and where do i do that where i declare them or when i give them their types?

Err actually, you don't need a pointer.

The function returns the calculated area so just assign that to your variable.

An example would be:

int i;
int input;

input = 5;
i = functionthatdoessomething(input);

printf("%d\n", i);

or, if you don't need to "save" the result:

int input;

input = 5;
printf("%d\n", functionthatdoessomething(input));

Sorry i did try it but i am not getting the result and i am still uncertain how this will work since i believe i would have to add the same lines of code(for the sum)everywhere i ask for the Area of rectangular/circular/semicircular.Can some1 else share his thoughts?

I think that you should indent your code properly. It is conventional for an indent level to be either one tab, or fixed number of spaces (two to eight).

Yes, so store the sum in its own variable

int sum;

sum = 0;

// ...

sum += Area_of_whatever();

// ...

sum += Area_of_whatever();

// maybe the above are in a loop... makes no difference

// after everything has been added to sum, print the result

What? You don't have 3 monitors and maximise every window you open? Odd.
