SQL stands for Structured Query Language, it is a standard query language that is used in a computer usually used for manipulation of data in a system through its database management by using its query codes or commands. It is widely used in database management and manipulation because it use a CRUD query method or Create, Update, Delete and Insert of data in the database.
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.
Answer:
Explanation:
To resolve this problem, first, we need the current date and a pass day, with these two values, we're going to use the formula called "DAYS" this formula returns the numbers of day between two dates, when we get the number of days, only we must multiply the result by 24, in this case, this represents the 24 hours in a day.
Explanation:
Wikis are defined as a form of a website or web page or a database where the users can work on the data, they can even add or edit the data. Wikis use a very quick as well as a easy syntax that allows the users to format the text and create various links between the pages. The users need internet browsers for that.
One of the main advantage of wiki is that it provides ability to collaborate asynchronously, and also without time constraints.Besides it also provides a beneficial function of something. It is free and not expensive.
