Answer:
The program written in Java is given in the explanation section
Explanation:
public class num9 {
//Defining the method CountCharacters()
public static int CountCharacters(char userChar, String userString){
int c = userString.length();
int count=0;
for(int i=0; i<c; i++){
if(userString.charAt(i)==userChar){
count++;
}
}
return count;
}
//Main method begins here
public static void main(String[] args) {
char n ='n';
String word = "Monday";
//Calling the method CountCharacters()
System.out.println(CountCharacters(n,word));
}
}
Answer:
1) SQL Server
SELECT Top 5 concate(first name,' ',last name) AS Full name, Current age AS Age, state AS Address, Phone number AS Contact number from actor ORDERBY Current age DSC ;
2) MySQL
SELECT concate(first name,' ',last name) AS Full name, Current age AS Age, state AS Address, Phone number AS Contact number from actor ORDERBY Current age DSC limit 5;
Explanation:
There two queries first having syntax works fine in SQL server and later with MySQL. All bold faced words are sql keywords. I assumed the tablename is actor as table name is not given if table name is any other replace actor with that name.
Answer:
EXAMPLE -
Create a variable and assign your age
var myage = 32;
type your age:
console.log(my age) ;
Notice that we did not type the actual numeric age. We used the variable instead. There wouldn’t be any purpose of declaring a variable if we were going to type 32 directly.
This makes the scrip more portable which means that the result on the screen is independent of the code console.log(myAge); . If we need to change our age all we have to do is to assign another number to the variable myAge and the output will change automatically. That’s the purpose of a variable.
