Answer:
B. Wearables.
Explanation:
These are tagged to be a category now in the technology as they are seen to make up the fifth type of personal computers in the question above. These are seen to be attached on the body or sometimes embedded to our outfit and also in other cases hung on a part of our body. They are counted to range from fitness trackers to smart watches, headsets etc. They are said to posses microprocessors which aid their functional ability through its use of the internet.
Answer:
The program to this question can be given as:
Program:
#include <iostream> //header file
using namespace std; //using namespace.
void SwapValues(int* userVal1, int* userVal2); //function declaration.
void SwapValues(int* userVal1, int* userVal2) //function definition.
{ //function body.
//perform swapping
int t = *userVal1;
*userVal1 = *userVal2;
*userVal2 = t;
}
int main() //main method
{
int n1, n2; //define variable
cout<<"Enter first number :"; //message
cin>>n1; //input by user.
cout<<"Enter second number :"; //message
cin>>n2; //input by user.
SwapValues(&n1,&n2); //calling function.
cout<<"Swapped values"<<endl;
cout<<"first number is :"<<n1<<endl; //print value
cout<<"second number is:"<<n2<<endl; //print value
return 0;
}
Output:
Enter first number :3
Enter second number :8
Swapped values
first number is :8
second number is :3
Explanation:
The description of the above C++ language program can be given as:
- In the program, firstly we include the header file. Then we declare and define a function that is "SwapValues()" function in the function we pass two integer variable that is "userVal1 and userVal2" inside a function, we define an integer variable that is "t" and perform swapping.
- Then we define the main function in the main function we define two variables that is "n1 and n2" this variable is used to take value-form user. then we pass this value to function and print the function values.
