I\'m relatively new to the C programming language, and I\'m trying to figure out how to create a function that can accept different types of data as parameters. The function is
In either case, you will need some sort of type-inferencing system to tell the C compiler which function to call. Which means, you will need to know, before-hand the type of array you might send in as a parameter to this "super function" of yours.
There is no "auto-type-inferencing" in C that can let you reflect upon the type of data at runtime. Better yet, you might have to write your own runtime environment for this to happen.
A slightly trivial hackish way to do this:
#include
size_t GetLengthOfArray(size_t sizeOfOneElementInArray, size_t sizeOfTheArrayInBytes)
{
return sizeOfTheArrayInBytes/sizeOfOneElementInArray;
}
int main(int argc, char *argv[])
{
char cArr[10] = {'A','B','C','D','E','F','G','H','I','J'};
int iArr[5] = {10,20,30,40,50};
printf("%d is the length of cArr\n%d is the length of iArr",GetLengthOfArray(sizeof(cArr[0]),sizeof(cArr)),
GetLengthOfArray(sizeof(iArr[0]),sizeof(iArr)));
return 0;
}
