Fibonacci Series Program using C Programming Language

 #include   <stdio.h>

int  main() {

printf( "Fibonacci Series \n" );

printf( "\n" );

int  i, number;

int  first, second, third;

printf( "Number of Terms (max. 16): " );

scanf( "%d" , &number);

printf( "\n" );

//limiting the Fibonacci Series

number = (number > 16 ? 16 : number);

if  (number < 0) {

printf( "Invalid Input \n" );

printf( "\n" );

return  1;

}

first = 0;

if  (number >= 0) {

printf( "fib(0)\t: %d \n" , first);

}

if  (number >= 1) {

printf( "fib(1)\t: %d \n" , second);

}

for  (i = 2; i <= number; i++) {

third = first + second;

printf( "fib(%d)\t: %d \n" , i, third);

first = second;

second = third;

}

printf( "\n" );
