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.

Answer:
False
Explanation:
A regular language can be represented by a regular expression. A regular language can be infinite. Let us consider a simple example of an infinite regular language:
a* is a regular language represented by a regular expression.
The languages matches all strings containing or more a's.
Clearly this is an infinite language.
Note that all finite languages are regular but all regular languages need not be finite.
Answer:

The capability to successfully utilize IT is mutually dependent on its ability to execute strategic strategy and set business goals. The ability to compete more and more relies on the capacity of an organization of using technology. In the future, what a company wants to do will rely on what its technologies can do.
