Find the error in the following code: The following code was intended for inputting scores for 20 students. If an invalid value was input, the program should keep reminding the user to re-input till a valid value is input. //Create Scanner object Scanner myScanner = new Scanner(System.in); //Declare variables final int studentNumber = 20; int scores[] = new int[studentNumber]; //Use while loop to allow user keep trying till valid input while(true) { for(int i=0; i
Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
Find the error in the following code:
The following code was intended for inputting scores for 20 students. If an invalid value was input, the program should keep reminding the user to re-input till a valid value is input.
//Create Scanner object
Scanner myScanner = new Scanner(System.in);
//Declare variables
final int studentNumber = 20;
int scores[] = new int[studentNumber];
//Use while loop to allow user keep trying till valid input
while(true)
{
for(int i=0; i<scores.length; i++) {
System.out.println("Score for student "+(i+1));
scores[i] = myScanner.nextInt();
if( 100 >= scores[i]>=0){
break;
}
//Otherwise continue the loop
} // end for
}//end while
