           }

I dont know what the error with this program ,please help me

the function name is different... the prototype has celsiusAtDepth and the definition has celsiusAtdepth...

float celsiusAtDepth (float);

float celsiusAtdepth ( float depth)

Read the error message - what does it say?

Also, please use code tags.

(Hing - check your spelling, capitalization counts.)

it did not run and the compiler said about the linking error sth

It will not run because it could not link. What does the linker error say? It should be telling you usefull information that will lead you to the solution.

RTFEM (Read The Full Error Message)

Generally a link error occurs when the linker cannot resolve a function to its declaration. The solution to this was already posted.
