Keep getting an error in C

Ok I'm trying to do these C practice exercises from this book and I keep getting this "Expected identifier or '('" error, this is what I wrote so far:

#include <stdio.h>

float fahrenheitFromCelsius(float cel);

{               //<-this line where the error shows up with the red stop sign

    float fahr = cel * 1.8 + 32.0;
    printf("%f Celsius is %f Fahrenheit.\n", cel, fahr);
    return fahr;

}

int main(int argc, const char * argv[])

{

    float freezeInC = 0;
    float freezeInF = fahrenheitFromCelsius(freezeInC);
    printf("Water freezes at %f degrees Fahrenheit.\n", freezeInF);

    return 0;
}

Remove the semicolon after the line float fahrenheitFromCelsius(float cel);. A semicolon ends statement, so you're getting that error because you're ending the function body before it begins.
