OBJECT: BASIC PROGRAMMING ON C++

THEORY:

Output operator
cout<<

            The identifier cout is a predefined object that represents the standard output stream in C++. The operator << is called the insertion or put to operator. In inserts (or sends) the contents of the variable on its right to the object on its left. If string represents a string variable then the following statement will display its contents.

            cout<<string;

E.g.:

LabTask1.1

#include<iostream.h>
int main()
{
float fahrenheit, celcius;
cout<<"Please input the temperature in Fahrenheit: ";
cin>>fahrenheit;
celcius=5/9*(fahrenheit-32);
cout<<"\nThe temperature in Celcius is: "<<celcius;
return 0;
}

Storing numbers dynamically n displaying them

 *      Here "dynamically" means a pointer with delete option

 *      We should have to store the numbers using a pointer in main function and at the end of the

 *      program we should have to clean or delete the memory used by the program.

Swapping Two Values using call by reference

#include<iostream.h>

void swap(int &, int &);

cout<<"Please input two numbers separated by space or an enter key: "<<endl;

cout<<"Your swapped number is: "<<endl<<a<<" and "<<b;

return 0;

}

void swap(int &pa, int &pb)

{

int temp;

temp=pa;

pa=pb;

pb=temp;

Return by Reference

* This program is suitable when we need to give some value for the greater value among two values.

cout<<"x= "<<x; //Here if you put the value of x which is less than y then it will displays the value of x.
//If you put the value of x which is greater than y then it will displays the value 10.

return 0;

Review of C

For this program, credit goes to my friend Suroj Karmacharya (SKAMMA)
