Please help with Challenge


Ok, so, i’ve written code as follows;

#include <stdio.h>
float remainingAngle(float angleA, float angleB);
return 180 - (angleA + angleB);

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

float angleA = 60.0;
float angleB = 30.0;
float angleC = remainingAngle(angleA, angleB);
printf("the remaining angle is %.2f\n", angleC);

return 0;


However, Xcode keeps highlighting my first { after then stdio.h and telling me "expected identifier or ‘(’, why is it doing this? I’ve tried multiple other codes and it gives this as well… confused!


Leave out the semicolon between the declaration of the function and the first curly brace:

float remainingAngle(float angleA, float angleB) {


lol that makes sense, thanks Aaron!
