On the demand of the students I am uploading some basic programs.Hope this will benefit you all.


// WRITE A PROGRAM TO ENTER TEMP IN FAHRENHIET AND CONVER IT IN CELCIUS
#include<iostream.h>
#include<conio.h>
void main()
{
float f,c;
cout<<"enter temp in fahrenheit"<<endl;
cin>>f;
c=5*(f-32)/9;
cout<<"The temp in celcius is:"<<c<<endl;
getch();
}

// WRITE A PROGRAM TO ENTER TWO NUMBERS AND SWAP THEM

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

int x,y,z;

cout<<"Enter two numbers"<<endl;

cin>>x>>y;

z=x;

x=y;

y=z ;

cout<<"The numbers after swapping:"<<endl;

cout<<"x is :="<<x<<endl<<"y is :="<<y<<endl;

getch();

}

// WRITE A PROGRAM TO ENTER TWO NUMBERS AND SWAP THEM WITHOUT USING THIRD VARIABLE

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

int x,y,z;

cout<<"Enter two numbers"<<endl;

cin>>x>>y;

x=x+y;

x=x-y;

y=x-y;

cout<<"The numbers after swapping:"<<endl;

cout<<"x is :="<<x<<endl<<"y is :="<<y<<endl;

getch();

}

//enter a four digit number and find the sum of first and last

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

int num,first,last,sum;

cout<<"enter a four digit number"<<endl;

cin>>num;

last=num%10;

first=num/1000;

sum=first+last;

cout<<"the sum of first and last digit is ="<<sum<<endl;

getch();

}
