Here we will see about the argument coercion in C or C++. The Argument Coercion is one technique by which the compiler can implicitly convert the arguments from one type to another type. It follows argument promotion rule. If one argument is lower datatype, that can be converted into higher datatypes, but the reverse is not true. The reason is if one higher datatype is converted into a lower datatype, it may loss some data.Let us see one pyramid that can express how the implicit conversion takes place.Example Live Demo#include using namespace std; double myAdd(double a, double b){    return a+b; ...
