Who taught a thing or two, genuflect is begged when parameters have a pointer might think, is the be-CodePudding

Write a function Calc (float firstNum, float secondNum, pSum float * and * float pDiff) implementation as addition and subtraction of two Numbers, the first two parameters are used for computing the operands, with default parameter values, the latter two parameter is a pointer, save and with poor results, respectively,
