Simply put, a typedef can be used as a pointer that references a function.Given below are the steps to implement typedefs in a Dart program.Step 1: Defining a typedefA typedef can be used to specify a function
typedef ManyOperation(int firstNo , int secondNo); //function signature Add(int firstNo,int second){ print("Add result is ${firstNo+second}"); } Subtract(int firstNo,int second){ print("Subtract result is ${firstNo-second}"); } Divide(int firstNo,int second){ print("Divide result ...
Many functions have the same signature, so we can use afunction pointerto point to all these functions with the same signature. Now the function helps pass functions as arguments to other functions. C language code for the understanding of the typedef function pointer #include <stdio.h>intsum(...
