PROGRAM TO FIND SQUARE ROOT OF A NUMBER

#include "stdio.h"
#include "conio.h"
main()
{
float a,b,e=0.00001,p,k;
clrscr();
textcolor(GREEN);
do {
printf(" ************************************************
);
printf(" PROGRAM TO FIND SQUARE ROOT OF A);
printf(" ************************************************
);
cprintf("ENTER A NUMBER(-1 to Quit) :");
scanf("%f",&k);

a=k;p=a*a;
while(p-k>=e)
{
b=(a+(k/a))/2;
a=b;
p=a*a;
}
printf("SQUARE ROOT IS = %f,a);
getch();
clrscr();
}
while(k!=-1);
getch();
}

  7. #include
    #include
    float SquareRoot(float num);
    void main()
    {
    float input, ans;
    clrscr();
    printf("\n Enter The Number : ");
    scanf("%f", &input);
    ans = SquareRoot(input);
    printf("\n Square Root : %f", ans);
    getch();
    }

    float SquareRoot(float num)
    {
    if(num >= 0)
    {
    float x = num;
    int i;
    for(i = 0; i < 20; i ++)
    {
    x = (((x * x) + num) / (2 * x));
    }
    return x;
    }
    }

  9. easy method is
    #include
    #include
    #include
    void main()
    {
    long int a,b;
    cout<<"a=";
    cin>>a;
    b=sqrt(a);
    cout<<"the square root of << a <<"is="<<b;
    }
    easy method

  10. can use clrscr();
    and getch();
    its is working tested.

    1. Hello, actually clrscr() is use to clear the screen (if it contains any previous text or output) & getch() is to just pause the screen, but if you uning DEV C/C++ then you dont need to use this, its useful in case of Turbo C...

History Of C..

In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.

My 1st Program...


#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}

Next Step...


#include
#include

void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");

printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");

getch ();

}

Hits!!!
