Answer:
Following are the code in the C programming Language.
//define function
void duplicate(char*argv, char**result) {
//set and initialize the variable to 0
int c = 0;
//set and initialize the char type pointer variable
char** t = argv;
//set the while loop
while(t){
//increment by 1
c++;
//increment by 1
t++;
}
//set malloc function in the pointer variable
result= malloc(sizeof(char)*(c+1));
//set the for loop
for(int i = 0; i < c; i++) {
//set malloc function in the pointer
(*result)[i] = malloc(strlen(argv[i])+1);
//copy the character from memory
memcpy(argv[i], (*result)[i], strlen(argv[i])+1)
;
}
//initialize null in the pointer
(*result)[i] = NULL;
}
Explanation:
In the following code, we define function "duplicate()" and pass two character type pointer arguments "*argv" and "**result" and inside the function.
- Set an integer type variable "c" and initialize to 0.
- Set character type pointer variable "t" and initialize the value of pointer variable "argv".
- Set the while loop and increment in the variable "c" and "t" by 1.
- Set the malloc function in the pointer variable "result".
- Set the for loop to copy the character from the memory.
- Finally, initialize the pointer variable "result" to NULL.

Answer:
D. All of these are correct
Explanation:
VoIP transmits voice data packets over the internet. It is a low-cost option for receiving personal and business calls because it uses existing infrastructure that is the internet to transmit calls, unlike traditional telephone systems that require specialized equipment such as PBXs that are costly.VoIP also offers the ability to have more than one telephone number, as long as the bandwidth is enough, it allows multiple connections at any given time.
