You define the doubling_time function as follows:
double doubling_time (double r) {
return 72.0 / r;
}
Here is what each part of the function definition does:
*--Tells C the data type of the returned value
|
| *-- Tells C the name of the function
| |
| | *-- Tells C the name and
| | | data type of the parameter
| | |
