Fibonacci Series Using an Array
We have now used a variety the features of C. This final example will introduce the array. The program prints out a table of Fibonacci numbers. These are defined by a series in which any element is the sum of the previous two elements. This program stores the series in an array, and after calculating it, prints the numbers out as a table.

#include

main()
{ int fib[24];
int i;

fib[0] = 0;
fib[1] = 1;

for(i = 2; i < 24; i++)
fib[i] = fib[i-1] + fib[i-2];

for (i = 0; i < 24; i++)
printf("%3d %6d\n", i, fib[i]);
}
One new construct has been introduced here.
int fib[24];
This defines an array called fib of 24 integers. In C, the array index is bounded by square brackets (this avoids confusion with a function call). Also, the first element of the array has index zero, and for this 24 element array, the last element is index 23.
