using namespace std;
main(){
//varibale declaration
//to create varibale using data type and name of varibale
//usual memory donot allocate for varibale
extern int number;
//varibale definition
//to create varibale using data type and name of varibale
//memory allocate for varibale
int age;
//varibale initialization
//to create varibale using data type and name of varibale and assign value to varibale
int salary=0;
float price=100.50;
// function cin and cout
// uss double less then simple with all cout and double greater then with cin
// Youtub not allowing me to add angle bracket
cout "Hello student";
cout "\nWhat is your age?";
cin age;
cout "Your age is "age;
//example-2
int marks=0;
cout "\n Enter your FSC Marks ";
cin marks;
cout "Your marks are "marks;
