Cannot convert float to float (calling function values inside another function

[baelec]

Hello all, first time poster here. I keep getting the following error when trying to calculate the average on line 142/143.
assignment3.1.cpp: In function ‘int main()’:
assignment3.1.cpp:142:97: error: cannot convert ‘float (*)(float, float, float, float)’ to ‘float’ for argument ‘1’ to ‘float reccalc(float, float, float)’
cout << "Your grade in the recitations section was:" << reccalc (designcalc, quizcalc, critcalc) << "%" << endl;


I am trying to make a simple grade calculator. I have only been using c++ for a couple of weeks so go easy on me :)

Please use code tags. It's really hard to read your code

designcalc is a function, and you're trying to pass it to a function that expects a number. Basically you're doing something equivalent to this:

float f();
float g(float);

g(f);
