Answer:
scanf() function is used to get a input from keyboard.This function is in the stdio.h library.To use this function we must include the stdio.h library first in the code. Then only we can use the scanf() function in any code.printf() function is used to print anything .this function is from stdio.h library.
Code to read voltage drop across the register.
#include <stdio.h>
// main function
int main(void) {
// variable
double vr1;
printf("Enter voltage drop:");
// read voltage drop from user
scanf("%lf",&vr1);
// print voltage drop
printf("voltage drop is:%0.2lf",vr1);
return 0;
}
Output:
Enter voltage drop:200.4
voltage drop is:200.40

Answer:
decreased drastically over the last five decades
Explanation:
I would say it is that answer because a few decades ago we needed huuuge computers that filled rooms to compute simple tasks. Now we have cellphones, which are basically computers that can fit into the palm of our hands. Our phones can do more than what those huge computers of the past did and they're easier to produce. So cost must have drastically decreased.
