Question

Please can someone help me with this using pseudocode and algorithm to compute the model:
A = √(s-b)(s-b)(s-c)
S = a+b+c/2
with explanation

Answer 1

step 1: Define a function (I am using this in the most general sense) ---lets call it CalculateArea ---which accepts inputs of type integer s, b and c.

Answer 2

The BODMAS/BIDMAS/BIRDMAS rule tells you: do what is in the brackets first, so
Step 2. subtract the value b from s and store in a temporary variable called A1
subtract the value b from s and store in a temporary variable called A2
subtract the value c from s and store in a temporary variable called A3
You will then need to multiply these values according to your formula so:
Step 3: multiply A1, A2 and A3 and store the result in a temporoary variable called M1
Finally, you will need to get the square root of M1, the result of multiplying these together
Step 4: get the square root of M1 and assign this to the variable A
Finally you will need to print out the value
Step5: Print the value of A to the screen.

leave out my comments and just include the steps, and you will have the pseudocode for the first equation.

Answer 3

Thanks for the answer........what about the algorithm of the equation?

Answer 4

From the pseudocode, we can deduce the algorithm as follows, (remember an algorithm is just a series of steps). Imagine you are trying to tell a computer how to do this.

Algorithm:
create a function called CalculateArea which accepts 3 integers called s,b,c
A1 = s-b
A2 = s-b
A3 = s-c
M1 = A1 x A2 x A3
A= sqrt (M1)
Print A;

Answer 5

@ubah
Isn't the Hero's formula meant to be:

\(\color{red}{s} = \color{red}{(a}+b+c\color{red}{)}/2\)
\(A = \color{red}{\sqrt{\color{black}{(s-\color{red}{a})(s-b)(s-c)}}}\)

In programming,
- upper/lower case count
- brackets count
- names of variables count
- order of statements counts
The compiler is not very forgiving, it does exactly what you tell it to do.
