Function Calls
Function calls are written with parentheses around the arguments, following the function name; commas separate arguments.
| Scheme: | (sqrt x) |
| Pascal: | sqrt(x) |
| C++: | sqrt(x) |
| Java: | Math.sqrt(x) |
A function with no arguments has empty parentheses in C++ and Java, but none in Pascal.
| Scheme: | (newline) |
| Pascal: | writeln |
| Java: | System.out.println() |
