Question : if three sides of a triangle are entered through the keyboard, write a program to check whether the triangle is valid or not. the triangle is valid if the sum of two sides is greater than the largest of three sides.

using namespace std ;
int main()
{
int n;
int sum =0;
cout<<"Enter a 5 digit number : ";

In this blog you you can learn how to how to make decimal to binary converter program.
process of conversion :-
source code :
#decimal to binary converter
def dec_bin(dec): #define function
binnum=[0]*dec #list created
i=0 #assign i for count
while dec > 0: #while loop
binnum[i] = dec%2 #logic part 1
dec = dec//2 #logic part 2
i += 1 #increase by 1
for j in range (i-1,-1,-1): #for loop for reverse the binary number to p
print(binnum[j],end="") #printing binary number
dec = int(input("enter the decimal number : ")) #take input through user
dec_bin(dec) #function calling..
Question :
Find sum of all digit of number :-
this problem is solved by two method :-
1st is without recursion method and
2nd is using recursion method
let's start ,
Without recursion method
step 1 :
make a function with name sumofDigit(num) : and pass the argument which is entered from the user
def sumofDigit(num):
step 2 :
we use while loop here for checking if num is grater then 0 is show in the code below :-
add=0
while num>0:
if the condition is True then we move to the next step
step 3 :
this step is totally on logic as shown below : -
add = add + num%10
num = num//10
print(add) #to print the result
step 4 :
in the step you come out from the function and call the function as shown below : -
num=int (input("enter the number : ")); #take input through user
sumofDigit(num) #function call
COMPLETE SOURCE CODE
1st method of without using recursion
#sum of 4 digit number without recursion
num=int (input("Enter the number : "))
add=0
while num>0:
add=add+num%10
num=num//10
print(add)
2nd Method using recursion
#sum of 4 digit using recurssion
def sdig(num):
if num==0:
return 0
return ((num%10) + sdig(num//10))
num=int (input("Enter the number : "))
print(f"sum of digit of {num} is {sdig(num)}")
Question :
write a function reverse_number () to return the reverse of the number entered.
Example :
Reverse_number(1234) display 4321
Source code :
def reverse_number (num):
add=""
while (num > 0):
n=num%10 # logic
num=num//10
add=str(add)+str(n)
print(add)
num = int (input("Enter the number : "))
reverse_number(num)
Instabot
In this session we learn how to upload picture using python library called instabot .
How to instabot on your pc .
step 1:
go to the START, search cmd then, press enter key
after that your command prompt is open as show in the given picture : -
step 2:
you have to type pip install instbot and press ENTER on the command prompt as shown in picture below : -
AFTER doing this all steps then your instabot is successfully installed on your pc . as shown in picture below : -
now go to the OPEN your IDLE and write the code below : -
Source Code
from instabot import Bot
bot=Bot()
bot.login(username= "yout username ",password="your password")
bot.upload_photo("C:/Users/ajay pandit/Desktop/UtubDownloader 18-03-2021 08_17_23.png" ,caption=" write caption here " )

Strong number is a special number whose sum of factorial of digits is equal to the original number. For example: 145 is strong number. Since, 1! + 4!

Positive integer greater than 1 which has no other factors except 1 and the number itself is called a prime number. 2, 3, 5, 7 etc. are prime numbers as they do not have any other factors. But 6 is not prime (it is composite) since, 2 x 3 = 6.
num=int(input("enter the numbr : "))
