Write a program to show your Desire text on screen:
#include <iostream.h>
#include <conio.h>
void main (void)
{
clrscr();
cout<<"My name is Padshah Gul."<<endl;
cout<<"I am student of Sarhad University."<<endl;
cout<<"I am from Afghanistan."<<endl;
getch();
}
Output of Program:
My name is Padshah Gul.
I am student of Sarhad University.
I am from Afghanistan.
Finding velocity of dram ( ∏∏∏∏r2.h):
#include <conio.h>
void main (void)
{
clrscr();
float h=8;
float r=5;
float pi=3.14;
float v=h*r*r*pi;
cout<<"Result is "<<v;
getch();

Using some arithmetic operations:
Like ( +, -, *, /, %)
#include <conio.h>
void main (void)

}
Output of the program:
Addition of 8 and 2 is = 10
Subtraction of 10 and 3 is = 7
Multiplication of 4 and 2 is = 8
Division of 10 and 2 is = 5

---------------------------------------------------------------------------------------------------------------------------------------------------------
