Implement the following two functions

/* returns Celsius equivalent of a Fahrenheit temperature (ft) */

double celsius(double ft);this part doesn't want to work check code please.

/* returns Fahrenheit equivalent of a Celsius temperature (ct) */

double fahrenheit (double ct);this part Done and works

Don't assume i know exactly what i have to change that's why I'm asking, I'm begineer and I'm just learning C. If i have anymore errors please let me know where to correct it. ThanksCode:#include <stdio.h> #include <stdlib.h> #include <math.h> double f2c(int f); double c2f(int i); int main ( void ) { int i, f; double Celsius, Fahrenheit; printf("\n\t Celsius<->Fahrenheit\n\n\n"); for ( i = 0; i <= 100; i += 2) { Fahrenheit = c2f(i); printf ( "\t%3d \t - %6.2f \n", i, Fahrenheit); } printf("\n\tFahrenheit<->Celsius \n"); for ( f = 32; f <= 212; f += 4) { Celsius = f2c(f); printf ( "\t%3d \t - %6.2f \n", f, Celsius); } system("pause"); } /*Implementation Fahrenheit to Celsius*/ double f2c(int f) { return (5.0 / 9.0) * (f - 32.0); } /*Implementation Celsius to Fahrenheit*/ /* NOT Working*/ /*What Exactly I need to change Here*/ double c2f(int i) return (9.0 / 5.0) * i) + 32; { }

[B]Errors I Get:[/B]
