Type Specifiers... It says I have the wrong one

int addTwo(int a, int b);

int foo = 2; int bar = 3;

int result = addTwo(foo, bar); printf ("addTwo %d", result);

int addTwo (int a, int b) { return a + b; }

Was doing the exercise and it says my one error is the wrong type specifier for printf("addtwo %d, result)

But don't see how it is....

Any help is much appreciated

first off, all the challenge wants is the function implementation, you dont need a prototype or anything else. all you need is the implementation. you are very close, you just need to change your return values and parameter types to floats:

float addTwo (float a, float b) {
return a + b;
}

the above code is all you need to write for the challenge, you dont need anything else
