A few common C++ problems

While working on C++ program you will get some error which are common ,let theme remove them

Problem:-Output window Close after blinking(Immediately)

Like you have write a program

#include<iostream.h>

int main()

{

                    int number1=100;

                    int number2=102;

                    int sum;

                    sum=number1+number2;

                    cout<<"Sum="<<sum;
                    return 0;

}

The output screen just blink and close 

Then use the  bold written code in your program

#include<iostream.h>

#include<conio.h>

int main()

{

                    int number1=100;

                    int number2=102;

                    int sum;

                    sum=number1+number2;

                    cout<<"Sum="<<sum;

                    getch();
                    return 0;

}
