1. |
Main function and header files are not mandatory part of a
program. |
Header files and main functions are essential part of every
program. |
|
2. |
Line termination semi-colon(;) is not required at the end of
every line to indicate the end of a line when each line of code
starts in new line. But if we want to write two or more lines of
code in one line then semi-colon requires. |
Semi-colon is necessary to terminate the line. |
|
3. |
Python uses indentation(4
spaces or one tab) to indicate code blocks. |
It uses curly braces to indicate code blocks. |
|
4. |
It takes advantage of modules(the python script with variable,
functions can be imported in another script). |
C++ takes advantage of header files and libraries to make code
sharable and reusable. |
|
5. |
We can start it from shell prompt by typing python and able to
type python expression directly without making files. But we can
also write the python script into files. |
Statements are saved into files then that are executed. |
|
6. |
While assigning values to variables data types are not written
at that time. Default user inputs are taken as strings and
converted to other types by python itself.
|
While declaring and assigning values to variables programmer
needs to write data types as essential part.
|
|
7. |
No increment and decrement operators in python. |
Increment and decrement operators are available. |
|
8. |
Allow to import packages for example math package. |
Built-in functions are imported through header files. |
|
9. |
It uses Dictionaries type which acts as structures in c++ and
lists same as array in c++ |
It uses structure type which is collection of elements of
different types and array collection of same type of data
elements. |
|
10. |
Python accepts single('), double(“) and triple(''' or
'''''') quotes to denote string literal and string should start
and end with same type.
|
C++ supports string literal encoded in double(“) quotes. |
|
11. |
Every line should be proceeded with hash(#) symbol to make that
comment. |
We can use single line and multi-line comments. |
|
12. |
We can use OS (operating system) module to perform directories
operations. |
Standard c++ don't have a library for directries. |
|
13. |
It provides smtplib module to send email to any other Internet
machine. |
It does not provides direct methods to send mails to other
Internet machines. |
|
1.
|
To print hello. |
print 'hello' |
#include<iostream>
using namespace std; main() { cout<<"hello"; } |
|
2. |
To add two numbers and to display a string.
|
a=raw_input("Enter value of A")
b=raw_input("Enter value of B") c=int(a)+int(b) print c name="satvir" print name |
#include<iostream>
using namespace std; int main() { using std::cin; using std::cout; int a,b,c; cout<<"enter value of a"; cin>>a; cout<<"enter value of b"; cin>>b; c=a+b; cout<<"Addition of two numbers :\t"<<c<<"\n"; string str="Satvir kaur"; cout<<str<<"\n"; return(0); } |
|
3. |
To import package like math. |
from math import *
print pi , e print sqrt(64) |
#include<iostream>
#include<math.h> using namespace std; int main() { using std::cout; using std::cin; cout<<"square roort of 64 is: "<<sqrt(64); return(0); } |
