Question

program HelloWorld (output); var n:real; k:integer; begin write ('introdu numaruol: '); readln (n); k:=sqrt n; writeln('K=',k); end.

Answer 1

Исправлено:

program HelloWorld;

var

n, k: real;

begin

write('introdu numaruol: ');

readln(n);

k := sqrt( n) ;

writeln('K=', k);

end.

Answer 2

It looks like you've provided a Pascal program that calculates the square root of a real number and assigns the result to an integer variable k. However, there is a small issue in your code. The sqrt function in Pascal returns a real number, but you're trying to assign it to an integer variable, which would result in a type mismatch error.

Here's the corrected Pascal program:

pascalCopy code
program HelloWorld (output);
var
  n: real;
  k: real;  // Change the type of k to real
begin
  write('Introduce a number: ');
  readln(n);
  k := sqrt(n);
  writeln('Square root of ', n, ' is ', k);
end.

In this corrected code, I changed the type of k to real to match the data type of the square root result (sqrt(n)). Now the program should work correctly by calculating the square root of the input number and printing the result as a real number.
