Answer:
Please find the answer below
Explanation:
// Online C compiler to run C program online
#include <stdio.h>
int main() {
// Write C code here
//printf("Hello world");
int userNum;
int i;
int j;
scanf("%d", &userNum);
/* Your solution goes here */
for(i = 0; i<=userNum; i++){
for(j = 0; j <= i; j++){
printf(" ");
}
printf("%d\n", i);
}
return 0;
}
Answer:
The sum of all positive even values in arr
Explanation:
We have an array named arr holding int values
Inside the method mystery:
Two variables s1 and s2 are initialized as 0
A for loop is created iterating through the arr array. Inside the loop:
num is set to the ith position of the arr (num will hold the each value in arr)
Then, we have an if statement that checks if num is greater than 0 (if it is positive number) and if num mod 2 is equal to 0 (if it is an even number). If these conditions are satisfied, num will be added to the s1 (cumulative sum). If num is less than 0 (if it is a negative number), num will be added to the s2 (cumulative sum).
When the loop is done, the value of s1 and s2 is printed.
As you can see, s1 holds the sum of positive even values in the arr
"Key logger" This could be software or hardware that does this.
Multiple inheritance causes Diamond problem which happens when:
Class A is parent of class B and C
Now when class D will be inherited from both Class B and C it will have all the members of class A and B which if same will confuse the compiler to import which one?
C++ solves it by using virtual keyword with them and thus telling the compiler which one to inherit.
Java has introduced the interface concept rather then allowing multiple inheritance.
The answers are 1, 3, and 5.
