Today we have to discuss about input and output function. By using these function we must declare header file which name iostream.
If You use iostream.h in dev c++ there must be an error during the compilation of the program.
So I suggest you to use #include<iostream> and then using namespace std.
Simple program of Dev c++.
#include<iostream>
using namespace std;
int main(){
cout<<“Hello World”
}
This gives Hello world output IDE.
Now we talk about the input function which means to take the value from the user and display on-screen by using cin function.
Now we discuss a simple program in which takes a number from user and print on the screen by using cin.
#include<iostream>
using namespace std;
int main(){
int num;
cout<<“Please Enter the Number”;
cin>>num;
cout<<“You enter :”<<num;
}
