Write the half function. a function call and the functionprototype
are provided.
void half(float *pv);
float value=5.0;
printf("value before half: %4.1f\n",value); // prints 5.0
half(& value);
printf("value after half: %4.1f\n",value); // prints 2.5

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.

}
