Answer:
#here is code in python
#recursive function to find nth Fibonacci term
def nth_fib_term(n):
#if input term is less than 0
if n<0:
print("wronng input")
# First Fibonacci term is 0
elif n==0:
return 0
# Second Fibonacci term is 1
elif n==1:
return 1
else:
#find the nth term of Fibonacci sequence
return nth_fib_term(n-1)+nth_fib_term(n-2)
n=int(input("please enter the term:"))
print(n,"th Fibonacci term is: ")
print(nth_fib_term(n))
Explanation;
Read the term "n" which user wants to know of Fibonacci sequence.If term term "n" is less than 0 then it will print "wrong input". Otherwise it will calculate nth term of Fibonacci sequence recursively.After that function nth_fib_term(n) will return the term. Print that term
Output:
please enter the term:7
7 th Fibonacci term is:
13
Answer:
D
Explanation:
Two dimensional array contain both rows and columns. Each row represented one record and each column represent one filed in that record.
for ex: int grades[5][3];
here array grades contains 5 rows and in each row we have 3 columns
if we have grades[i][j] then " i " represents number of rows and j represents the number of columns in that row.
j<grades[i].length represents i=0 to 2[here no of columns are 3, array index starts from 0 to 2]
The Answer is D
I'm pretty sure it's the last
Answer:
Electrons move through the wires is the opposite direction.
Explanation:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
#include <iostream>
#include <fstream>
using namespace std;
int main(){
int x, sum=0;
ifstream f("numbers.txt");
while(!f.eof()){
f >> x;
sum +=x;
}
cout << "Sum : " << sum;
}
