Answer:
// here is code in C++(bmi.cpp).
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
float weight,height;
cout<<"enter the weight(in kilograms):";
//read the weight
cin>>weight;
cout<<"enter the height(in meters):";
//read the height
cin>>height;
// calculate the bmi
float bmi=weight/(pow(height,2));
// print the body-mass index with two decimal places
cout<<"BMI is: "<<fixed<<setprecision(2)<<bmi<<endl;
return 0;
}
Explanation:
Read the weight from user and assign it to variable "weight",read height and assign it to variable "height".Then find the body-mass index as (weight/height^2).Here weight should be in kilograms and height should be in meters.
Output:
enter the weight(in kilograms):75
enter the height(in meters):1.8
BMI is: 23.15
What is referred to the description above is the term SELECTIVE ATTENTION. When there is selective attention, there are certain memories that are only selected and these are processed to become part of the short-term memory. Not everything that is being sensed is remembered.
Answer:
b
Explanation:
First, we need to initialize the classifier.
Then, we are required to train the classifier.
The next step is to predict the target.
And finally, we need to evaluate the classifier model.
You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.
However, you need to know how these classifier works. And its explained before:
You need to initialize the classifier at first.
All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.
The predict(x) returns the y which is the predicted label.And this is prediction.
For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.
Answer:
Written in Java
public static void printArray(int myarr[], String s){
for(int i = 0; i<myarr.length;i++){
System.out.print(myarr[i]+s);
}
}
Explanation:
This defines the static method alongside the array and the string variable
public static void printArray(int myarr[], String s){
The following iteration iterates through the elements of the array
for(int i = 0; i<myarr.length;i++){
This line prints each element of the array followed by the string literal
System.out.print(myarr[i]+s);
}
}
The method can be called from main using:
<em>printArray(myarr,s);</em>
Where myarr and s are local variables of the main
