C :: Fahrenheit To Celsius Scale Converter

One of the questions requires writing up a code, that converts Fahrenheit scale to Celsius scale.

The relation between temperature in ◦ C and ◦F is given by the formula:

◦C = 5/9 . ( ◦F - 32 )

Write a program that prints a table (just two columns without any borders) with temperature in ◦F and ◦C for temperatures between 0 and 300 ◦F in steps of 20◦. Compile and run your program. I wanted to approach this problem via arrays and for loops, and I wrote up this

Code:
#include<stdlib.h>
#include<stdio.h>
int main() {
// begin main()
// units
double[] celsius = new double[ 16 ];
double[] fahrenheit = new double[ 16 ];

[Code] ....

Now when I'm trying to compile that, the compailer throws an error which makes absolutely no sense to me.

Code:
fahrenheitCelsius.c: In function ‘main’:
fahrenheitCelsius.c:18:9: error: expected identifier or ‘(’ before ‘[’ token
double[] celsius = new double[ 16 ];

[Code] ....
