Fibonacci series means a series of numbers in which each number is the sum of the two preceding numbers. Example is 1, 1, 2, 3, 5, 8<\/p>\n\n\n\n
Below is C program code to print Fibonacci series as per user input. <\/p>\n\n\n\n
for e.g if user input 20 then program will print 20 elements in Fibonacci series.<\/p>\n\n\n\n
