Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int x=5,y=2,z=9;
int min;
// find the smallest value and assign to min
// if x is smallest
if(x < y && x < z)
// assign x to min
min=x;
// if y is smallest
else if(y < z)
// assign y to min
min=y;
// if z is smallest
else
// assign z to min
min=z;
// print the smallest
cout<<"smallest value is:"<<min<<endl;
return 0;
}
Explanation:
Declare and initialize variables x=5,y=2 and z=9.Then check if x is less than y and x is less than z, assign value of x to variable "min" .Else if value of y is less than value of z then smallest value is y, assign value of y to "min".Else z will be the smallest value, assign its value to "min".
Output:
smallest value is:2
the undo option is the right answer
Answer: Wow that's really cool!
Answer:
columns, rows
Explanation:
In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.
Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.
These data can be stored or organized in a database management system through the use of multiple-column record formats.
In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.
