Python Basic

1. Hello world program in Python IDLE:-

print("hello world");

sentence="there is a boy";

print(sentence);

print(sentence.replace("boy","girl"));

print(sentence);

print(sentence[1:4]);

print(sentence.upper())

print(sentence.lower())

2. Loop in python :-

n=0

print("this is a program to find sum of first 100 numbers")

for i in range(5):

    i=i+1

    n=n+i

print('the sum is ' + str(n))

4.Example program:-

print('what is your name?')

name=input()

print('hello ' + name)

x=len(name)

print('number of characters in your name is:' + str(len(name)))

print("enter a number")

num1=input()

print('you entered  '+num1)

5. Example 4  

# Store input numbers

num1 = input('Enter first number: ')

num2 = input('Enter second number: ')

# Add two numbers

sum = float(num1) + float(num2)

# Display the sum

print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

Static Data Member Function :-

#include<iostream>

using namespace std;

class A

{

    static int count;

    int num;

public:

    void getdata(int a1)

    {

        num=a1;

        count ++;

    }

    void getcount ()

    {

        cout<<"count:"<<count<<endl;

    }

};

int A:: count;  //definition of static data

int main()

{

    A a,b,c;

    a.getcount();

    b.getcount();

    c.getcount();

    a.getdata(100);

    b.getdata(200);

    c.getdata(300);

    cout<<"after calling " <<endl;

    a.getcount();

    b.getcount();

    c.getcount();

    return 0;

}

Constructor :-

#include<iostream>
using namespace std;
class a
{
    int m,n;
public:
    a() //constructor
    {
        m=1;
        n=2;
    }
void display()
{
    cout<<"m="<<m<<endl;
    cout<<"n="<<n<<endl;
}
};
int main()
{
    a o;        //object o is created of class a and constructor is called automatically
    o.display();
    return 0;
}

#include<iostream>

using namespace std;

class gce

{

    int m,n;

public:

    gce(int x, int y);  //decleration of constructor

    void display()

    {

        cout<<m<<n<<endl;

    }

    gce()

    {

    }

};

gce :: gce(int x=1,int y=2) //definition of constructor outside class first gce is class name and other is function name

{

    m=x;

    n=y;

}

int main()

{

    //gce g;

    gce g=gce(10,20);

    //gce g(10,20);

    g.display();

    return 0;

Node MCU & Arduino : Microcontroller for IoT devices

Node MCU (ESP8266)  is a microcontroller having similar function as Arduino which has many advantages over Arduino UNO i.e. Low cost,integrated support for wifi networks, small , low power consumption.

C++ Programming with Technical Akash | Conditionals and Loops

To print table of any number ; input of the number is taken by the user ; using for loop

#include<iostream>
using namespace std;
int main()
{
    float i;
    int x;
    cout <<"table of any number" <<endl <<"enter the number whose table is to be write" <<endl ;
    cin>> i;
    for(x=1;x<11;x++)
    {
        cout <<x <<"x" <<i <<"=" <<x*i << endl ;
    }
    return 0;
}

while loop

#include<iostream>

using namespace std;

int main()

{

    int i=1,j;

    cout <<"enter the last number" <<endl ;

    cin>>j;

    cout <<"this is our counting from 1" << endl;

    while(i<=j)

       {

             cout<<i <<endl;

                i++;

       }

}

output

do while loop

#include<iostream>
using namespace std;
int main()
{
    int a,b;
    cout << "enter the first and last number " <<endl;
    cin>>a;
    cin>>b;
    int c =a;
    cout<<"the series is " <<endl;
    do
    {
        cout<< c <<endl;
        c+=2;
    }
    while (c<=b);
}

output

C++ With Technical Akash | Data type , Array and Pointers

Array basic example

#include <iostream>
using namespace std;
int main()
{
    int a[]={3,5,4,6,7};
    cout<< a[3];
}

output

While loop in in array;

#include<iostream>

using namespace std;

int main()

{

    int a[]={2,4,45,5,35,46,4567,567,57,567,45,75,};

    int b=0;

    do

    {

      cout <<a[b] <<endl;

      b+=1;

    }

    while (b<6);

}

C++ with Technical Akash | Function

* A function is  a group of statements that can perform a particular tasks.
But how we was performing the tasks without knowing about function ? Actually we was using a function named "main" function . A c++ program must have at least one function.
We can reuse function and we can modify it somewhere in program.

#include<iostream>
using namespace std;
int akash()
{
    cout<< "technical akash will solve your all problems";
}
int main()
{
    akash();
}

Here int is called function return type which must be defined , and akash is function name which is further recalled in int function.

=> we can also modify functon after defining it , see below a example :-

#include<iostream>

using namespace std;

int akash()

int main()

{

    akash();

    akash();

}

int akash()

{

    cout<< "technical akash will solve your all problems"<<endl;

    cout << "this is our modified function "<<endl;

}
