double two(double, double)
char three (int, int char, double);

I need a statement for the function test with the actual parameters 5, 5,7.3, and 'z'
please help

test ( 5, 5, 7.3, 'z' ) will work.
And, What is your question?

Then you cant possibly expect help. And also, I over looked the code before.
