import java.util.Scanner;
public class U2_L3_Activity_Four {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence.");
String sent = scan.nextLine();
int count = 0;
for (int i = 0; i < sent.length(); i++){
char c = sent.charAt(i);
if (c != ' '){
count++;
}
else{
break;
}
}
System.out.println("The first word is " + count +" letters long");
}
}
We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!
<u>Answer:</u>
I am writing <em>partial code in</em> <em>c++ to calculate weighted average</em>. The weighted average should be calculated based on multiplying the test score and its <em>respective weight and finally add all the test score.</em>
<u>Explanation:</u>
<em>int arrtestscore[100];</em>
<em>int arrweight[100];</em>
<em>int n;</em>
<em>double weightedavg;</em>
<em>cout<<”Enter the number of test score for which weighted average needs to be calculated”;</em>
<em>cin>>n;</em>
<em>for(int x = 0; x <n;x++)</em>
<em>{</em>
<em> cout<<”Enter test score :” + (x+1) ;</em>
<em> cin>>arrtestscore[x];</em>
<em> count<<”Enter the respective weight:”;</em>
<em> cin>>arrweight[x];</em>
<em>}</em>
<em>for (int i=0; i<n;i++)</em>
<em>{</em>
<em> weightedavg = weightedavg + (arrtestscore[i] * arrweight[i])</em>
<em>}</em>
<em>cout<<”weighted average = “ <<weightedavg; </em>
Answer:
Top/bottom conditional formatting
Explanation:
The top/bottom conditional formatting automatically carries out the task of finding the highest, lowest and even average values.
Conditional formatting formatting gives one the opportunity to enhance reports and dashboards as they work on excel.
You use the too/bottom formatting to highlight cells whose values of highest in a dataset and lowest in a dataset
Answer
Abstraction enables GPS system to facilitate the utilization of well defined interfaces while offering room to add additional levels of functionality which are complex to handle.
Explanation
GPS system applies abstraction to be able to arrange level of complexity on which a user will interact with the system. For example, it establishes a link of satellite positioned and timed systems to allow a radio receiver obtain a signal in four dimension after synchronizing the data of latitude, longitude, attitude and time.
Answer:
mobility and broad reach
Explanation:
The two major characteristics of mobile computing are:
Mobility: It basically refers to the portability. Mobility means that users can carry their mobile device wherever they go. This facilitates real-time communication with other devices. Users can take a mobile device anywhere and can contact with other devices and systems via a wireless network for example a user, wherever he happens to be, can log in to his email account to check his emails using his mobile phone.
Broad Reach: It basically means that the mobile device users can be reached at any time. This means that the users of an open mobile device can be instantaneously contacted. Having an open mobile device means that it can be reached by or connected to other mobile networks. However mobile users also have options to restrict specific messages or calls.
