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
Yes you do have to program it first.
Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group
