I would really like to understand, please explain using C programming language. Thank you

1 Write a program that takes a decimal integer number as input and convert it to corresponding binary number and octal number. You are required to write functions for the conversion and call it from the main function. You can use as many functions as you want. For conversion techniques, check the following links- 2 Fibonacci Sequence is the series of numbers, where each number is the sum of two preceding numbers of the series. These numbers are represented by F(n), where F(n) is the n-th Fibonnacci number. Such a sequence of length 6 is 1,1,2,3,5,8. Thus, formula to calculate the n-th Fibonaaci number is- F(n)-F(n -1) + F(n -2); where F(0)-0 and F(1) 1 Write a program takes a positive integer, n as input and prints the Fibonacci sequence of length n. You might want to write a user defined function to find the n-th Fibonacci number and call it from the main function for all integers from 1 to n to print the sequence. You can use recursion if you want. For this code, you need to use both loop and function
