Nth Term of Fibonacci Series in C++ | Nth Term

Nth Term of Fibonacci Series in C++. In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and are characterized by the fact that every number after the first two is the sum of the two preceding ones.

Fibonacci Series: 1 ,1 ,2 ,3 ,5 ,8 ,13 ,21 ,34.

Often, especially in modern usage, the sequence is extended by one more initial term.

Fibonacci Series: 0 ,1 ,1 ,2 ,3 ,5 ,8 ,13 ,21 ,34.

Nth Term of Fibonacci Series in C++

#include <iostream>
using namespace std;
int main()
{
	int range, first = 0, second = 1, fibonicci;
	cout << "Enter the Range for Terms of Fibonacci Sequence " << endl;
	cin >> range;
	cout << "Fibonacci Series upto " << range << " Terms  " << endl << endl;
	for (int c = 0; c < range; c++)
	{
		if (c <= 1)
			fibonicci = c;
		else
		{
			fibonicci = first + second;
			first = second;
			second = fibonicci;
		}

		cout << fibonicci << "  ";
	}

	return 0;
}

1. C Program For Remove All Vowels From A String

C Program to Count Vowels, Consonants, Digits and Spaces in Given String

Problem:- C program to count the number of vowels, consonants and so on or C Program to Count Vowels, Consonants, Digits and Spaces in Given String or Find Number of Vowels, Consonants, Digits and White Space Characters or C Programming Notes: Counting vowels, consonants, digits, special character or C Program to Count words, vowels, letters, digits, spaces, Characters or Program to Find the Number of Vowels, Consonants, Digits and Whitespace in a String in C or Count the number of vowels, consonants, digits etc or C program to Count Vowels, Consonants, Digits, Spaces from String.

Check This:- Hacker rank solution for Strings, Classes, STL, Inheritance in C++.

Explanation:- for Counting the vowels, constant, digits and white space in c is very simple we have to just put an if else condition for each query. As we can see that there are 4 query(vowels, constant, digits and white space) so we have 4 counter separate for each of them and for finding the vowels in a string or sentence if simple just put the 5 character in lower and upper case and compare with the input string if any character matches then increase the vowels counter and same for constant and digit, for a single iteration of a string any one of the counters should be increased. last counter for white space, and at the end print the all 4 counters values, total counter values is equal to the size of the string.

Also Check:- Geeksforgeeks solution for School, Basic, Easy, Medium, Hard in C++.

Solution:-

#include<stdio.h>

int main()

{

/*Visit - www.programmingwithbasics.com*/

printf("=====================================");

printf("\nVisit - www.programmingwithbasics.com");

printf("\n=====================================");

char line[1000];

int i, v, c, ch, d, s, o;

o = v = c = ch = d = s = 0;

printf("\n\nEnter a Line of String: \n\n");

gets(line);

for(i=0;line[i]!='\0';++i)

{

if(line[i]=='a' || line[i]=='e' || line[i]=='i' || line[i]=='o' || line[i]=='u' || line[i]=='A' || line[i]=='E' || line[i]=='I' || line[i]=='O' || line[i]=='U')

++v;

else if((line[i]>='a'&& line[i]<='z') || (line[i]>='A'&& line[i]<='Z'))

++c;

else if(line[i]>='0'&&c<='9')

++d;

else if (line[i]==' ')

++s;

}

printf("\n\nOutput Is Below\n\n");

printf("\n\nTotal Number of Vowels Are: %d",v);

printf("\nTotal Number of Consonants Are: %d",c);

printf("\nTotal Number of Digits Are: %d",d);

printf("\nTotal Number of White spaces Are: %d\n\n",s);

return 0;
