Write a program in C++ to print Addition of Two Numbers" 

    
#include<iostream.h>
#include<coniog.h> 


int main()
{
       int integer1,integer2,sum;

/*If user want to print the output as
Sum of integer1 + integer2 = Sum then our cout statement will look like
cout<<"sum of"<< integer1 << "+" << integer2 << "is ::"<<sum;

My five-year journey of pursuing a Ph.D. in Oracle APEX has been filled with both challenges and invaluable learning experiences. I decided to write this blog to share my insights and to help those who are considering a Ph.D. and are in search of a compelling research topic.   Where did the idea come from? It all started with a simple Online Test Application on a Local Area Network (LAN) using Oracle APEX . The idea of pursuing a Ph.D. in Oracle APEX first came to me in 2011-12.During that time, I developed an application to conduct online MCQ tests for students, designed to run on the LAN. Using a standard computer with minimal configuration, I installed Oracle APEX and set up the application so that students could access the MCQ test on the intranet, allowing us to generate results instantly. ...

This blog will demonstrate steps to display TextField dynamically based on Table Columns in Classic Report and insert data into database. Oracle APEX has a large collection of API in which APEX_ITEM.TEXT is used in this example while if you want to explore in detail just click on following link. https://docs.oracle.com/cd/E14373_01/apirefs.32/e13369/apex_item.htm#AEAPI192 Step1: Create a Classic Report based on SQL Query. In this demo i have used a Emp table. So my query look like as follows.     select EMP.EMPNO as EMPNO,               EMP.ENAME as ENAME     from EMP EMP and Result will look like as shown in following figure. Now If we need to display a textbox against each employee name we need to add one dynamic APEX_ITEM.Text. So now our query will change as follows. select  EMP.ENAME as ENAME,    APEX_ITEM.TEXT(01,null,NULL,2,NULL,'Emp_Salary') AS Salary,    APEX_ITEM.HIDD...
