The answer that best completes the statement above is this: <span>signs, barricades, drums, cones, tubes, flashing arrow panels, and flag individuals. The main purpose of these traffic control devices is to signal the drivers to stop or to slow down and to change lanes most especially in areas that are undergoing construction.</span>
It's true because you can get a better understanding when looking at the evidence.
Answer:
// code to read grade
#include <stdio.h>
// main function
int main(void) {
// if grade is character
char grade;
// if grade is numeric then we can use int or double
// int grade;
// double grade;
printf("Enter your grade:");
// read grade from user
scanf("%c",&grade);
// print grade
printf("your grade is:%c",grade);
return 0;
}
Explanation:
To read a value, scanf() function is used from stdio.h.Read a grade from user and assign it to variable "grade".
Output:
Enter your grade:A
your grade is:A
// code to read die volt
#include <stdio.h>
// main function
int main(void) {
// variable
double die_volt;
printf("Enter die volt:");
// read die volt from user
scanf("%lf",&die_volt);
// print die volt
printf("Entered die volt is:%0.2lf",die_volt);
return 0;
}
Explanation:
Read the die volt from user and assign it to variable "die_volt" with the help
of scanf() function.
Output:
Enter die volt:220
Entered die volt is:220.00
Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
