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
Answer:
A binary system is a system that functions on zeros and ones (0's and 1's).
A decimal system is an Arabic numeric system that has 10 as its base and uses a dot which is also called a decimal point to show fractions.
Differences
- A decimal uses ten different digits which is 0-9 while a binary system uses just two digits 0 and 1
- Decimal system was historically a Hindu-Arabic system while the binary system is just an Arabic system
Similarities
- They are capable of performing arithmetic operations
- They both can be represented in decimal form
