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.
I think I am not sure that it is probably b
Answer:
The answer to this question is given below in the explanation section.
Explanation:
You can find a single number or name in a large worksheet containing thousands of numbers and names using the find and replacement feature in excel.
You can use Ctrl+F keyboard shortcut for finding and replacing features. When you press Ctrl+F, a dialog will get open, using this dialog, you can find the required number or name while entering in the search text box. Then, click on the Find button, if the worksheet matches the result, give you the matched result in the yellow highlighted color.
Also, you can use Ctrl+F to replace a name or number with some other name or number.
Alternatively, you can do this using the home tab, then find the option find and select under the editing group of commands.
Answer:
private ip addresses
Explanation:
A private ip address is assigned to each device on a network, allowing devices on the same network to communicate with each other without using any public ip addresses.
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.
