Pros: Readability. Unique closing reserved words on compound
statements will enhance readability and flexibility of a language. When an
endwhile or an endif in a program is written by someone else, it is vivid which
block is ending. Using braces is much harder is sometimes much harder to read.
Cons: Writability. They have the disadvantage of writability
and thus, complicating the language by increasing the number of keywords. Use
of more of these reserved words mean less words available for the programmer.
Answer:
/*
* Program to write data to text file.
*/
#include<iostream>
#include<fstream>
#include<string.h>
using namespace std;
int main()
{
//Variable to name and age of a person.
string name;
int age;
cout<<"Enter your name"<<endl;
cin>>name;
cout<<"Enter your age"<<endl;
cin>>age;
//Creating object of ofstream.
ofstream file;
file.open ("outdata.txt");
//Writing data to file named outdata.txt
file<<name<<" "<<age;
file.close();
}
Output:
Enter your name
John
Enter your age
25
Content of Output.txt:
John 25
Explanation:
To write data to a file ofstream object is used. An ofstream object file is created first and then using this object a file named "outdata.txt" is created.
Finally using shift operator (<<), by means of operator overloading, name and age of person is transferred to file outdata.txt.
Answer:
age = int(input("Enter your age: "))
charge = 0
if age > 55:
charge = 10
if 21 <= age <= 54:
charge = 15
if 13 <= age <= 20:
charge = 10
if 3 <= age <= 12:
charge = 5
if 0 <= age < 3:
charge = 0
print(charge)
Explanation:
*It is in Python.
Ask the user for the age
Check the each given range and set the charge accordingly using if statements
Print the charge
