Expert's answer

#include <iostream>

float sqrlt( float x )

{

float result = 0;

// calculate square

result = x*x;

//Show result

std::cout << "square=" << result <<"\n";

return result;

}

int main()

{

float x;

//Show message:

std::cout << "Enter number:\n";

//Read number:

std::cin >>x;

float square;

//call function

square=sqrlt( x );

return 0;

}

float sqrlt( float x )

{

float result = 0;

// calculate square

result = x*x;

//Show result

std::cout << "square=" << result <<"\n";

return result;

}

int main()

{

float x;

//Show message:

std::cout << "Enter number:\n";

//Read number:

std::cin >>x;

float square;
