It is not possible to do that with the system function. Assuming you are going to be executing in a POSIX-style shell where > is the shell … Read more

Each of the parameters are being used to find particular X and Y values. O changes from 0 to pi in steps of pi/8 while Vo, t and g remain unchanged. The t variable is simply an array from 0 to 5 in steps of 1 and so there are 6 time points defined all … Read more

Swift enumeration cases are defined as case someName, not case .someName. This is an easy syntax error when declaring a new enum’s cases, as in most other situations you will be typing .someName via dot syntax. But when first declaring that enum case, it’s case someName without the period. enum SomeEnum { case one case … Read more

While making a function virtual in c++ where do I have to write virtual keyword? In the function declaration, before the function name, and after any attribute specifiers, along with the other specifiers (including the type specifier for the function’s return type). The general syntax for a declaration is simple-declaration: decl-specifier-seq<opt> init-declarator-list<opt> ; attribute-specifier-seq decl-specifier-seq<opt> … Read more

Your first code reads as $a = false; if ($a) { echo ‘A’; } if (false) { echo ‘B’; } else { echo ‘C’; } When you do not use braces, only the next statement (statement, not line) gets executed as part of that control structure. It is not ambiguous as this behaviour is clearly … Read more
