Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct
Keyboard would be the correct answer
Answer:
Option D is correct.
Explanation:
The Digital Revolution applies to technological improvements from optical automated and mechanical machines to that of the digital technology that is currently accessible. The era began well into the year of 1980s, and continues. That Digital Revolution still marked as the start of the Era of Info.
- It's the evolution of electrical and analog to digital technologies.
- Its the advent of digital technologies has also altered the manner of people communication.
- The following things are only done through computers, cellphones, as well as the web.
Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.
Explanation:
Some examples are:
call by value
#include <stdio.h>
void swap(int, int);
int main()
{ int a = 10, b= 20;
swap(a, b);
printf("a: %d, b: %d\n", a, b);
}
void swap(int c, int d)
{
int t;
t = c; c = d; d = t;
}
OUTPUT
a: 10, b: 20
The value of a and b remain unchanged as the values are local
//call by reference
#include <stdio.h>
void swap(int*, int*);
int main()
{
int a = 10, b = 20;
swap(&a, &b); //passing the address
printf("a: %d, b: %d\n", a, b);
}
void swap(int *c, int *d)
{
int t;
t = *c; *c = *d; *d = t;
}
OUTPUT
a: 20, b: 10
due to dereferencing by the pointer the value can be changed which is call by reference
The answer is the alu arithmetic logic unit.
