Beginner practicing

This is an example of an error that I get on most code that I just don't understand.

Here's the code:

Code:

---

#include <stdio.h>
#include <stdlib.h>


float convert (float f);


int main()
{
    float temp_f;
    float temp_c;


    printf("What is the temperature in fahrenheit: ");
    scanf("%.2f", &float temp_f);


    printf("The temperature in fahrenheit is %.2f", temp_f);
    return 0;
}

---

The error is: error: expected expression before 'float'.

As mentioned above I get this alot and originally I didn't have the & in the scanf function, which I thought was the problem, but it gave me the same error even after adding it. Any ideas? (I am using Code::Blocks ver. 20.03)

You just need to remove the word 'float' from the scanf call.

Thank you for the reply. I'm just curious as to why the compiler states "expected expression before float" because that to me says there's nothing wrong with having float itself there, but you're just missing something before the word float? Is that just something you have to get used to in working with these compilers?

Yes. Compiler error messages can be a little weird. :tongue:

It could be that you are trying to take the address of a key word and the compiler is looking for an expression that it can take the address of.
