Small Help Please🥺 Function Oriented in C++

Question

Kindly check if my code is correct with the logic of the problem to make my code better.
thank you

Problem: Write a function-oriented program that emulates the sqr() function. Display the square root values of input N.

Thank you.🙏

heres my code: https://code.sololearn.com/cSlDTS9yW2G8/?ref=app

Answer 1

#include<stdio.h>
#include<iostream>
using namespace std;
float sqr(int n){
float temp,sqt;
sqt=n/2;
temp=0;
while(sqt!=temp)
{
temp=sqt;
sqt=(n/temp+temp)/2;
}
return sqt;
}

int main()
{
int n;
float res;

printf("Enter a Number: ");
cin >> n;

res = sqr(n);

printf("The square root of %d is %f",n,res);

return 0;

}

Thank you sir.

Answer 3

Thank you so much for your advice sir I'm still learning this functions on c++ ...thank you for helping me appreciate a lot🙏❤️

Answer 4

use void instead of float when creating a function
as there are no return value.

Answer 5

And you have used c functions like scanf, printf you are using cpp compiler so you should use cout(for print) and cin(for input) function for input output operation

Answer 6

Instead of printing result in function, return to calling statement. Like
cout << sqrt(9) ; // will output 3
Similarly write for cout << sqr(9) ;

So take input in main, and pass to sqr function and get result back..
Hope it helps..

Answer 7

Thank you sir Bob_Li🙏

Answer 8

raf
Several mistakes.
The sqr function have no return value. float sqr is expected to return a float.
Do the input and output handling in the main function.

Answer 9

Which compiler you are using c Or cpp?
