Answer:
words.hasNext()
Explanation:
Given the code snippet below:
- while (inputFile.hasNextLine()) {
- String word = "";
- String line = inputFile.nextLine();
- Scanner words = new Scanner(line);
- while (words.hasNext()) {
- word = words.next();
- }
- System.out.println(word); }
- }
We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.
The name of the command prompt executable is cmd.exe so just type that.
Answer:
#include <iostream>
using namespace std;
struct StudentType{
string studentName;
int studentId;
}
int n;
char answer[20];
int main(){
cout<< "Enter the size of the array: ";
cin >> n;
StudentType *student = new StudentType(n);
for (int i = 0; i < n; i++){
int name;
int number;
cin>> name;
cin >> number;
student[i].studentName = name;
student[i].studentId = number;
}
for (int i = 0; i < 20; i++){
cout<< "Enter answers: ";
cin >> ans;
answer[i] = ans;
}
}
Explanation:
The C++ source code has three global variables namely, answer which is an array of character data type, StudentType which is a structure data type and the integer variable n. The main function declares and initializes the dynamic-spaced student array of the structure datatype with the n variable.
