Addition of Two Numbers in Python in Linux

A simple program that I wrote using Python programming language that will ask the user to give two numbers and then the program will compute the sum of two numbers and display the results using Python programming language.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me in the following email address for further details. If you want to advertise on my website kindly contact me also in my email address also. Thank you.

Display User Names Using List in Python

A simple program that I wrote using python to accept a series of names and display the user names using list data structures in Python programming language.

Program Listing

data = []

print("\tDisplay User Names Using List in Python")
print("\n")
while True:
    data.append(input("Enter the name : "))

    choice = input("Enter another name?? (y/n) : ")
    if choice.casefold() == 'n':
        break

print("\n")
for user_names in data:
    print(user_names);
print("\n")
print("\tEnd of Program")
print("\n")

Subtraction of Two Numbers Without Using Subtraction Operator in Java

A simple program to ask the user to give two numbers and then the program will compute the difference of two numbers without using subtraction operator in Java programming language.

Program Listing

import java.util.Scanner;

public class subtract_two_numbers {

public static void main(String[] args) {

int val1=0,val2=0;

Scanner input_val= new Scanner(System.in);

System.out.println("\n");

System.out.println("\tSubtraction of Two Numbers Without Using Subtraction Operator in Java");

System.out.println("\n");

System.out.print("\tEnter the first number : ");

val1=input_val.nextInt();

System.out.print("\tEnter the second number : ");

val2=input_val.nextInt();

int subtract = val1+(~val2+1);

System.out.println("\n");

System.out.println("\tThe difference between " + val1 +

" and " + val2+ " is " + subtract + ".");

System.out.println("\n");

System.out.println("\tEnd of Program");

System.out.println("\n");
