Input devices accept data in a form that the computer can use; they then send the data to the processing unit. The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want.
I hope this helps you:)
Answer:On average, the cost of a robust custom software project will range between $50,000 and $250,000, although some sources say the price of a hypothetical mobile app built by a large development company may reach $1,000,000.
Explanation:
There are some typos in this question as the numbers become too large and lead to undefined during calculations.
so the correct data is:
Songs = 12
Rock = 15
Blues = 20
Disco = 15

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
