Here's a C++ code snippet: #include <bits/stdc++.h> using namespace std; int main() { int n=50; int arr[n]; cout << "Enter 50 integers: "; for (int i = 0; i < n; i++) cin >> arr[i]; cout << endl; sort(arr,arr+n); for (int i = 0; i < n; i++) { cout << "pair which gives sum equal to " << arr[i] << " is:"; for (int j = 0; j < n; j++) for (int k = j + 1; k < n; k++) if (arr[i] == arr[j] + arr[k]) cout << "(" << arr[j] << " & " << arr[k] << ")" << ","; cout << endl; cout << "*******************************" << endl; } return 0; } The program will gather 50 integers from the user, sort them in ascending order, and identify all pairs that total to any of the array's elements, followed by printing those pairs.
Answer: Random fluctuations.
Explanation: A time series consists of data points ordered chronologically, arranged in equal intervals. Typically, this data sequence is systematic and has defined intervals. However, there’s no allowance for randomness, making unpredictable variations, or random fluctuations, absent in such series. Thus, option (D) is the correct choice.
The primary issue was declaring int prod within the while loop, which caused prod to reset to 1 each time the loop executed.
Answer:
Below is the Python code with suitable comments.
Explanation:
#Input file name acquisition
filename=input('Enter the input file name: ')
#Opening the input file
inputFile = open(filename,"r+")
#Dictionary definition.
list={}
#Read and split file content using a loop
for word in inputFile.read().split():
#Check if the word exists in the file.
if word not in list:
list[word] = 1
#Increment count by 1
else:
list[word] += 1
#Closing the file.
inputFile.close();
#Output a blank line
print();
#Sorting words according to their ASCII values.
for i in sorted(list):
#Display unique words along with their
#frequencies in alphabetical order.
print("{0} {1} ".format(i, list[i]));
Answer:
#include <iostream>
using namespace std;
int main() {
int i, lo=12, hi=45, result=0; // initializing the required variables..
for(i=lo;i<=hi;i++) // implementing a for loop.
{
result+=i; // accumulating the sum of integers..
}
cout<<result<<endl; // displaying the resulting total.
return 0;
}
Output:-
969
Explanation:
This program is written in C++. Initially, the variables i, lo, hi, and result are declared, with only lo, hi, and result initialized. A for loop is employed to loop through all values from lo to hi, adding each integer to the result.
