int a[5]={2,0,1,1,4},

b[5]={4,2,1,-1,2}; It is two massives of real and imagine part of 5 complex digits/ So i need to transform it to the trygonometric form for that reason there is function trigonom. And also to multiply this complex (in usual form) among them. So this raw code need very correction as even declaration of function recall the compilation errors/ The bad isues that i have not found any exaples of trygonometric form of complexs numbers in the net/ Moreover even multiplication function need the using of massisves. So it is very uneasy task but I would be pleased to get help as C newbie.
