Write a function f which takes three pointers to int variables (a, b, c). Then it should:-Set the first variable to the sum of values of the variables (a + b + c).-Set the second variable to difference between maximum and minimum of values ( max(a,b,c) - min(a,b,c) )-Set the third variable to median of a, b, c.For example:if a = 5, b = 10, c = 2Then f(&a, &b, &c) should:Set a to 17 (that is the sum)Set b to 8 (that is max - min = 10 - 2)Set c to 5 (that is the median of 5, 10 and 2)
NOTE: You are already provided a test main which checks your code for evaluation. DO NOT MODIFY IT or your answer will NOT be accepted.
#include<stdio.h>
// Write your code here...
//////////////////////////////////////////// THIS IS THE TEST MAIN FOR YOUR PROGRAM// DO NOT MODIFY IT!!int main() {int a = 1;int b = 2;int c = 3;for (int i = 0; i < 2; i++) {f(&a, &b, &c);printf("%d\n", a);printf("%d\n", b);printf("%d\n", c);}return 0;}//////////////////////////////////////////…
In C++, If you had the double-pointer above and also had these variables:
type x, * q;
And had executed these statements:
q = &x; p = &q;
How would a function given p by value be able to change the contents of x?
Write a program in c languageto find the sum of all non-prime numbers from m and n (including m and n also) using the concept of passing pointers to function. Pass addresses of m, n and sum integers from the main () function to the user defined function: calculate () [Function is not returning any value], and display the sum in the main () function.
