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:
Following is the program in the python language
st = 'sAN RaN' #String
print(st.lower()) #display into the lowercase
Output:
san ran
Explanation:
Following are the description of program
- Declared and initialized the string in the "st" variable .
- The lower function in python is used for converting the uppercase string into the lower case string .
- Finally in the print function we used lower function and display the string into the lower case
MCKibben argues that the inhabitable planet is shrinking because:
- Consistently higher temperatures will likely make certain areas uninhabitable
- Desertification will reduce the amount of harvestable land
- Coastlines are being lost to sea level rise.
<h3>What is Shrinking?</h3>
This is the process in which an object or place becomes smaller as a result of various activities.
The most suitable options which explains why the planet is shrinking is as a result of a reduction in the areas in which humans can live as a result of the factors mentioned above.

Pinhole cameras were one of the most sophisticated devices of the period, it made tasks much easier it basically worked exactly like the human eye and is something just like tracing.
