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 <iostream.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();

Height= 8 cm

2r=10 cm





}

Using some arithmetic operations:

Like ( +, -, *, /, %)

#include <iostream.h> #include <conio.h> void main (void) { clrscr(); int p,s,m,d,r; p=7+5; s=10-3; m=4*2; d=10/2; r=11%5; cout<<"output of arithmetic operators"<<endl; cout<<endl<<"Addition of 8 and 2 is = "<<p<<endl; cout<<"Subtraction of 10 and 3 is = "<<s<<endl; cout<<"Multiplication of 4 and 2 is = "<<m<<endl; cout<<"Division of 10 and 2 is = "<<d<<endl; cout<<"Remainder of 5/2 is = "<<r<<endl; getch(); } 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





Remainder of 5/2 is = 1

Temperature Calculation:

Convert Celsius to Fahrenheit:

Convert Fahrenheit to Celsius:

#include <iostream.h> #include <conio.h> void main(void) { clrscr(); cout<<endl<<endl<<"\t\t\t Temperature Calculation"< <endl; cout<<"\t\t\t"<<endl; cout<<endl<<endl<<"\t0-------------0"<<endl; cout<<"\tl Well Come!! l"<<endl; cout<<"\t0-------------0"<<endl; cout<<endl<<endl<<"\t\convert Fahrenheit to Celsius "<<endl; float c,f; cout<<endl<<endl<<"\tPlease Enter you Temperature i n Fahrenheit = "; cin>>f; c=(f-32)*5/9; cout<<endl<<endl<<"\tYour Temperature in Celsius is = "<<c; cout<<endl<<endl<<"\t============================== ================================ "<<endl; cout<<endl<<endl<<"\t\ it "<<endl; cout<<endl<<endl<<"\tPlease Enter you Temperature i n Celsius = "; cin>>c; f=(c*9/5)+32; cout<<endl<<endl<<"\tYour Temperatures in Fahrenhei t is = "<<f; cout<<endl<<endl<<endl<<"\t\tO=========== 0"<<endl; cout<<"\t\tl Thank you l"<<endl; cout<<"\t\t0===========0"<<endl;
