Answer:
It create a new file in which writing of data begins.
Explanation:
A file can be open in the three mode:
-r (Read mode): open an existing file for the purpose of reading data from it.
-w (write mode): Create a new file for the purpose of writing data to it.
-a (append mode): open an existing file for the purpose of appending extra data to it but if the file does not exist, it create a new file and start writing data to it.
A. Since it tells about how people think she’s lesser because she’s a women.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int minn=INT_MAX;
int maxx=INT_MIN;
int n1,n2,n3,n4,n5;
cout<<"enter five Numbers:";
//read 5 Numbers
cin>>n1>>n2>>n3>>n4>>n5;
// find maximum
if(n1>maxx)
maxx=n1;
if(n2>maxx)
maxx=n2;
if(n3>maxx)
maxx=n3;
if(n4>maxx)
maxx=n4;
if(n5>maxx)
maxx=n5;
// find minimum
if(n1<minn)
minn=n1;
if(n2<minn)
minn=n2;
if(n3<minn)
minn=n3;
if(n4<minn)
minn=n4;
if(n5<minn)
minn=n5;
// print maximum and minimum
cout<<"maximum of five numbers is: "<<maxx<<endl;
cout<<"minimum of five numbers is: "<<minn<<endl;
return 0;
}
Explanation:
Declare two variables "minn" & "maxx" and initialize them with INT_MAX and INT_MIN respectively.Then read the five number from user and compare it with "minn" & "maxx" ,if input is greater than "maxx" then update "maxx" or if input is less than "minn" then update the "minn". After all the inputs, "minn" will have smallest and "maxx" will have largest value.
enter five Numbers:5 78 43 55 12
maximum of five numbers is: 78
minimum of five numbers is: 5
Answer:
The answer to this question is given below in the explanation section.
Explanation:
Betty is developing a machine learning algorithm that looks at a vast amount of data that is collected over 100 years, and She also wants to check the relationship among variables such as humidity, temperature, and rainfall in the given data.
So, the correct answer to this question is b. She is developing an association machine learning algorithm.
Because the association tells the relationship between variables. She used the association to find the relationship among variables such as humidity, temperature, and rainfall.
While the other options are not correct because:
Regression is used to find out the cause and effect relationship between dependent and independent variables. Big data is the biggest field of data analysis, so this option does not best suit this context. Classification is used to classify data, or organizing data into their related group. While clustering is the task of dividing the population into a number of groups such that populations in the same groups are more similar to other populations in the same group than those in other groups. so these are all incorrect options to this question except the "b" option i.e association.
