Answer:
import numpy as np
word = input("Enter a word: ")
acc = []
with open("Downloads/record-collection.txt", "r") as file:
lines = file.readlines()
for line in lines:
if word in line:
line = line.strip()
acc.append(int(line[0]))
if np.mean(acc) >= 2:
print(f"The word {word} is a positive word")
print(f"{word} appeared {len(acc)} times")
print(f"the review of the word {word} is {round(np.mean(acc), 2)}")
else:
print(f"the word {word} is a negative word with review\
{round(np.mean(acc), 2)}")
Explanation:
The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.
The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.
Answer:
Program is as follow:
Explanation:
#include<iostream.h>
#include < conio.h>
bool isVowel(char b)
{
return
( b=='a' || b=='A' || b=='e' || b=='E' || b=='i' || b=='I' || b=='o' || b=='O' || b== 'u' || b=='U');
For swaoing the vowels
string reverseVowel ( String str)
{
int j = 0;
string v ;
for ( int i= 0 ; str [i]]!='0'; i++)
if( isv(str[i]))
v[j++] = str[i[;
for ( int i = 0; str[i]! = '0' ; i++
if ( isv (str[i]))
str{i} = v [--j]
return str;
}
int main ()
{ string str = " Programming";
cout<<swapv(str);
return 0 ;
}
Answer:
Decline Stage
Explanation:
The decline stage is the stage after attaining maturity in the product life cycle. At this point, the product begins to lose its value in sales as a result of poor acceptance or an entry of a better substitute for it. This gives rise to loss in profit and a gradual halt in demand.
