Series Printing coding 4

CODE NO:- 16

Q)Write a program to display the Fibonnaci series 0,1,1,2,3,5,8,13,21.....

#LOGIC
Here we need to add the two previous term to get next term.

NOTE: Considering starting index as 0 (zero).

For example: we got 1 by adding 1 and 0 i.e we got 2nd term by adding  1st term and 0th term.

#Program (In C):

In  C language we use  ' // '  for Single line comment and /*---*/ for multi line comment

APPROACH 1: Using RECURSION

 #include<stdio.h> int fibo(int); // function prototype void main() { int n,i; printf("\n enter no.of terms:"); scanf("%d",&n); for(i=0;i<n;i++) { printf("%d, ",fibo(i)); // function call } return 0; } int fibo(int a) // function body { if(a==0) return 0; else if(a==1) return 1; else return fibo(a-1)+fibo(a-2); // recursive call }

We got this output by using DEV C++ (IDE)


APPROACH 2: Using LOOP

#include <stdio.h>
int main() 
{
    int i, n, t1 = 0, t2 = 1, nextTerm;
    printf("Enter the number of terms: ");
    scanf("%d", &n);
    printf("Fibonacci Series : ");

     for (i =0; i<n; ++i)
{
        printf("%d, ", t1);
        nextTerm = t1 + t2;
        t1 = t2;
        t2 = nextTerm;
    }
    return 0;
}

We got this output by using DEV C++ (IDE)

WHY PROGRAMMING?

                                                                                 Following are the reasons why we should learn programming : 1>"Because it makes you think". 2>"It makes you understand what technology really means ." 3>"It is just like a superpower that any hero has and can be achieved by any one of us." By programming, we can make a machine (robots etc.) to do a work what we want from them to do by just giving instructions. example-instruction given to a robot to walk.  "you need not have to be a genius  but a determinant person"                                               " programmers of today are the wiza...

Series code 2

CODE NO:- 06 Q)Find the no. for a user given position for this series  0,0,2,1,4,2,6,3,8,4,…     For example: (1) At position 4 you should get no. :1                             (2) At position 9 you should get no. :8 #LOGIC According to the given series, we can conclude that : 1) At even indexes, we are having a series which starts from 0 and gets incremented by (+2) . 2) At odd indexes, we are having a series which starts from 0 and gets incremented by (+1) . NOTE : Here we are considering 0 as starting index. #Program  (In C++): #include<iostream> using namespace std; int main() { int n,t; cout<<"\n enter the position :"; cin>>n; if(n%2==0) { n=n/2; t=(n-1); cout<<"The no. at given position is:"<<t; } else { n=n/2+1; t=(n-1)*2; cout<<"The...

Pattern Printing coding 7

CODE NO:- 09 Print the below pattern #LOGIC Take a variable and assign it with value n+2 and print this value using the inner loop whereas in the outer loop decrement the value by 1. Here n is the no. of entered rows whereas n+2 is the first element of the pattern. ex: if n=4 then n+2 result 6. #Program( In C): In    C language we use  ' // '  for Single line comment and /*---*/ for multi line comment #include<stdio.h> // header file for i/p and o/p int main() { int n,i,j,k,a; printf("\n enter the no.of rows:"); scanf("%d",&n); a=n+2; for(i=0;i<n;i++) {           for(k=0;k<n-i;k++)   { printf("%d ",a);           }           a--;// decrementing value by 1 printf("\n"); } return 0; } We got this output by using DEV C++ (IDE) Link: For ot...
