Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.
import java.util.Scanner;
public class JavaApplication42 {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int count = 0;
System.out.println("Enter an integer between 0 and 100");
int num = scan.nextInt();
if (num <= 0 || num >= 100){
System.out.println("error");
}
else{
while(num <= 100){
if (count == 20){
System.out.println("");
count = 0;
}
else{
System.out.print(num+" ");
count++;
num++;
}
}
}
}
}
I hope this helps!
