Answer:
require direct line-of-sight scanning.
Explanation:
Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.
Answer:
1. multiplying two numbers when you meant to add them - Logical Error
2. dividing by zero - Compile time error
3. semi colon at the end of a programming statement - Logical error
4. wrong in output - Run time error
5. when you should have typed a - Compile time error
6. producing inaccurate results - Logical error or Run time error
Explanation:
Compile time error is a lack in computer programming which causes to violate the rules which are defined by user in the program.
Run time error produces wrong outputs. It causes lags in the softwares which makes the output inefficient. It even causes programs crash when the output is just seconds away.
Logical error is the situation where programs completes the task assigned but with the wrong syntax. The output is produced with some abnormality.
Answer:
printStars(35);
Explanation:
public class Question {
public static void main(String args[]) {
printStars(35);
}
public static void printStars(int numberOfStars){
for(int i = 1; i <= numberOfStars; i++){
System.out.print("*");
}
System.out.print("\n");
}
}
You actually have the correct answer. An excel formula starts with = so your answer would be =4*6
