This C Program generates fibonacci series. In fibonacci series the first two numbers in the Fibonacci sequence are 0 and 1 and each subsequent number is the sum of the previous two. For example fibonacci series is 0, 1, 1, 2, 3, 5, 8,13, 21…………
Here is source code of the C program to generate fibonacci series. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

int fib1 = 0, fib2 = 1, fib3, limit, count = 0;

printf("Enter the limit to generate the Fibonacci Series \n");
scanf("%d", &limit);
printf("Fibonacci Series is ...\n");
printf("%d\n", fib1);
printf("%d\n", fib2);

while (count < limit)
{
fib3 = fib1 + fib2;
count++;
printf("%d\n", fib3);
fib1 = fib2;
