A hiden mistake in my code

I am doing the temperature challenge part 1, and i am literally stuck on the last step,.

My code:

#include

int main() {
double tempf = 84;
double tempc = (tempf - 32)/1.8;
std::cout << “The temp is " << tempc << " degrees Celsius.\n”;
}

Error: You did not execute the correct file, or your output is not correct.
Output: You did not execute the correct file, or your output is not correct.
Task((5): Now execute the output file using the terminal.

my prompt: g++ temperature.cpp
my second prompt: ./a.out

You are referring to the exercise Challenge: Temperature (Part 1)

Can you include a screenshot which shows your code, your terminal, the check mark for step 4 and the error message being displayed? Perhaps it may reveal some clues.

Something similar to the screenshot below,

here.

// Your output:
"The temp is 5.55556degrees Celsius"

// It should be:
"The temp is 5.55556 degrees Celsius."
