WebThe syntax to declare a new variable in C++ is straightforward: we simply write the type followed by the variable name (i.e., its identifier). For example: 1 2 int a; float mynumber; These are two valid declarations of variables. The first one declares a variable of type int with the identifier a. WebSquaring something is just multiplying it by itself, and thus we want the sqrt of a*a + b*b - hence sqrt (a*a + b*b);. Once again the 'expression' type functionality comes in handy as the simpler mathematics is first evaluated to give the result, and then this is passed to the sqrt function and square rooted to give us the result.
