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.
Answer: Falsifiability
Explanation: Falsifiability is the term that is defined as the evaluation of any particular hypothesis or theory to be proven wrong .This feature gives the access that the theory can be tested and have more accurate claims .
The ESP(Extrasensory perception) theory can also have feature of being falsifiable because the experiments and test lead to the issue that the negative effects of the theory are not certain which might occur due to simple observation of effects.
Answer:
Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
Answer:
this:name = 'John'
print("Is name == 'John'? I predict True.")
print(name == 'John')
print("\nIs name == 'Joy'? I predict False.")
print(car == 'Joy')
this:age = '28'
print("Is age == '28'? I predict True.")
print(age == '28')
print("\nIs age == '27'? I predict False.")
print(age == '27')
this:sex = 'Male'
print("Is sex == 'Female'? I predict True.")
print(sex == 'Female')
print("\nIs sex == 'Female'? I predict False.")
print(sex == 'Joy')
this:level = 'College'
print("Is level == 'High School'? I predict True.")
print(level == 'High School')
print("\nIs level == 'College'? I predict False.")
print(age == 'College')
Conditions 1 and 2 test for name and age
Both conditions are true
Hence, true values are returned
Conditions 3 and 4 tests for sex and level
Both conditions are false
Hence, false values are returned.
