Answer:
C code for half()
#include<stdio.h>
void half(float *pv);
int main()
{
float value=5.0; //value is initialized
printf ("Value before half: %4.1f\n", value); // Prints 5.0
half(&value); // the function call takes the address of the variable.
printf("Value after half: %4.1f\n", value); // Prints 2.5
}
void half(float *pv) //In function definition pointer pv will hold the address of variable passed.
{
*pv=*pv/2; //pointer value is accessed through * operator.
}
- This method is called call-by-reference method.
- Here when we call a function, we pass the address of the variable instead of passing the value of the variable.
- The address of “value” is passed from the “half” function within main(), then in called “half” function we store the address in float pointer ‘pv.’ Now inside the half(), we can manipulate the value pointed by pointer ‘pv’. That will reflect in the main().
- Inside half() we write *pv=*pv/2, which means the value of variable pointed by ‘pv’ will be the half of its value, so after returning from half function value of variable “value” inside main will be 2.5.

The Jenkins tool is often used by DevOps to facilitate the development, testing, and deployment of new software.
<h3>What is software development?</h3>
The practice of conceptualizing, planning, designing, coding, documenting, testing, and bug-fixing that went into building and maintaining applications, platforms, or other software modules is known as software creation.
Jenkins is a Java-based continuous integration/continuous delivery and deployment system that is free and open-source.
Thus, the Jenkins tool is often used by DevOps to facilitate the development, testing, and deployment of new software.

Answer:
Communication is a constant process and it can also be corrupted.
Explanation:
Communication is the ability to send and receive messages that can be understood. We constantly communicate with our environment verbally and or orally, using signs and language to express ourselves.
Messages sent can and should be decoded for communication to be complete. It can be corrupted on its path to the decoder, this hinders understanding.
I do believe the answer is c. I used to own a computer with a windows 7 program.
