Answer 1

Option 1:-

/*

* C program to calculate square root of a number

* using sqrt function

*/

#include <stdio.h>

#include <math.h>
 
int main () {

    double x, result;

    printf("Enter a number\n");

    scanf("%lf", &x);        result = sqrt(x);

    printf("Square root of %lf = %lf\n", x, result);        return 0;

}


Option 2:-

#include<iostream.h>

 #include<conio.h>

#include<math.h>

void main()
{

int num,ans;

clrscr();

cout<<"Enter any Number: ";

cin>>num;

ans=sqrt(num);;

cout<<"\n Squre of "<<num<<" is: "<<ans;

getch();

}  

Output:- Enter a Number: 16
Square root of 16 is: 4
