Explanation:
I have notes on it we learned it in 8th
Answer:
The program to this question as follows:
Program:
//header file iostream
#include<iostream> //including file for use basic function
//using name space
using namespace std;
//main method
int main() //defining main method
{
int a[3][3]; //defining two dimension array
int x,y,sum=0; //defining variables
cout<<"Enter array elements: "<<endl; //message
for(x=0;x<3;x++) // for row
{
for(y=0;y<3;y++) //for column
{
cin>>a[x][y]; //input values from user.
}
}
//loop for calculting sum.
for(x=0;x<3;x++)
{
for(y=0;y<3;y++)
{
sum=sum+a[x][y];//add all elements
}
}
cout<<"Sum: "<<sum; //print sum.
return 0;
}
Output:
Enter array elements:
1
2
3
4
5
6
7
8
9
Sum: 45
Explanation:
In the above C++ programming language code first, a header file is included then the main method is declared, inside a main method 2D array that is "a[][]", and an integer variable is defined that are "i, j, and sum". In the next line for loop is used, this loop is used two times that can be described as follows:
- The first time it is used for inserting elements from user ends.
- The second time, it uses the sum variable to add all array elements. and in the last print function that is "cout" is used for print sum variable value.
That is false. are you doing it on a computer course. <span />
Answer:
ip = enrollment + section;
Explanation:
The variable ip has been declared to be a pointer to int.
int * ip;
The variable enrollment has been declared as an array of 20 elements .
int enrollment[20];
The variable section has been declared as an int.
int section;
In order to make ip point to the element in the array indexed by section, we can use the following statement :
ip = enrollment + section;
This will make ip point to enrollment[section].
The missing word here is social.
Social engineering involves using simple human methods to steal data, such as looking through peoples’ drawers for pieces of paper on which they might have written down passwords, or perhaps sneaking a look at the keys you press while walking past your desk as you are typing your password. Such behaviors designed to steal your personal information are methods of social engineering.
