Answer:
Don't forget to close any parentheses you open. Other then that everything looks fine, I just polished it a little bit
Explanation:
name = input("What is your first name? ")
print("Hello", name)
age = int(input("How old are you? "))
print("In 10 years you will be", (age+10))
print("In 20 years you will be", (age+20))
print("5 years ago you were", (age-5))
Answer:
The recommended type of trunk for interoperability is an IEEE 802.1Q trunk.
Explanation:
IEEE 802.1Q is an open industry standard and is the most commonly implemented on layer 2 switches of different vendors, assuring interoperability.
Commonly know as <em>dot1q</em>, is the networking standard that supports virtual LANs (VLANs) on an IEEE 802.3 Ethernet network. It specifies the mechanisms for tagging frames with VLAN data and the procedures for handling this data by switches and bridges.
The real-valued function whose value is to be either minimized or maximized subject to the constraints defined on the given LPP over the set of feasible solutions. The objective function of a LPP is a linear function of the form z = ax + by.
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.
