function help

so i want to figure out what is wrong with the challenge, i always get the return error as unqualified id. can someone help here's the question:

Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments. It should add the two arguments together, and return the result. (No need to write the main function. Just write out the implementation for the addTwo function.)

here's what i put down

float addTwo; { float a = 25; float b = 20;

printf("this is the total %d\n", addTwo); }

return float;

Here is a shell of what your function should look like:

returnType functionName(dataType argumentOne, dataType argumentTwo) {

return something;


your function needs to return the sum of the 2 variables passed in as arguments.

you dont need to print anything out. you dont need to define any local variables inside the function.
