Answer: Dereferencing a variable that is not a pointer

Explanation:

The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.

Some of the reasons for a fatal execution-time error include:

• Dereferencing a pointer that has not been initialized properly

• Dereferencing a null pointer

• Dereferencing a pointer that has not been assigned to point to a specific address.

It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.

If there is no index.html file in the root folder nothing will be displayed when you navigate to the site address
MAVERICK [17]
This can be a tricky question because this could be true or false depending how the Web Server is setup. For instance, with the Apache web server you do not need an index.html file as long as you have a index.htm file or an index.php file. So the answer could be false if you have one of the other files. Anyways, I think they mean an index file in general so the answer is true.

Write the half function. A function call and the functionprototype
EastWind [94]

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.

Output:

Output is given as image.
