Answer:
Option A is the correct choice answer for the above question.
Explanation:
The programming concept says that every function returns some value. If the return value is not defined by the user then the function returns the garbage value otherwise it returns the defined value by the user.
The return value is defined by the user with the help of the "return" statement and with the help of the following syntax-
return value; // The return statement.
Hence the option A is right because it satisfies the above concept while the other is not because--
- Option B states that it must be longer than one line which is not correct.
- Option C states that it cannot be longer than one line but this line does not make any sense about the returned statement.
- Option D states that it describes the parameter value which is the wrong definition about the returned statement.
I would suggest the answer would be both A and D, mail merge is used to specify different field for different recipients.
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.
