I say about Lite C,not purl C.
void populate_array(int *array, size_t arraySize, int (*getNextValue)(void))
{
for (size_t i=0; i<arraySize; i++)
array[i] = getNextValue();
}
int getNextRandomValue(void)
{
return 0;
}
this will be show syntax error!

I remember having a similar issue but you can do things like this in lite-c. Give me a minute, I'll give it a try!

have a look:
#include <acknex.h>
//
void populate_array(int * array, int arraySize, void * getNextValue)
{
int i;
for(i = 0; i < arraySize; i++)
{
int TempFunction(); // temporary function
TempFunction = getNextValue; // set function pointer
array[i] = TempFunction(); // execute function
}
}
int getNextRandomValue(void)
{
return (int)(random(1000));
}
void main()
{
fps_max = 60;
random_seed(0); // initialize random seed
//
int MyArray[8]; // create array
populate_array(MyArray, 8, getNextRandomValue); // fill array with return values of function "getNextRandomValue()"
printf("Array Content: (%d, %d, %d, %d, %d, %d, %d, %d)",
MyArray[0], MyArray[1], MyArray[2], MyArray[3],
MyArray[4], MyArray[5], MyArray[6], MyArray[7]);
}
It's a strange work-around but it works. Note that this is a lite-c-only thing, I don't think this would work in C.

i try it,but script is crash!
#include <acknex.h>
//
void populate_array(int * array, int arraySize, void * getNextValue)
{
int i;
for(i = 0; i < arraySize; i++)
{
int TempFunction(); // temporary function
TempFunction = getNextValue; // set function pointer
array[i] = TempFunction(); // execute function
}
}
int getNextRandomValue(int a)
{
return a*a;
}
void main()
{
fps_max = 60;
random_seed(0); // initialize random seed
//
int MyArray[8]; // create array
populate_array(MyArray, 2, getNextRandomValue); // fill array with return values of function "getNextRandomValue()"
int TempFunction(int a);
TempFunction = MyArray[0];
int res = TempFunction(2);
printf("%d",res);
}

thank you for your answer! but i want to use this code likes:
void PrintfText(int value)
{
printf("Hello World %d!/n",value);
}
void CallPrintfText(void (*callfuct)(int),int value)
{
callfuct(value);
}
int main()
{
CallPrintfText(PrintfText);
return 0;
}

as you've seen in my example, you have to use that little workaround.
void PrintfText(int value)
{
printf("Hello World %d!/n",value);
}
void CallPrintfText(void * callfuct,int value)
{
void func(int);
func = callfunct;
func(value);
}
int main()
{
CallPrintfText(PrintfText);
return 0;
}
I don't think there's another way using lite-c.

#include <acknex.h>
#include <default.c>
void PrintfText(int value)
{
printf("Hello World n%d!",value);
}
void CallPrintfText(void * callfuct,int value)
{
void func(int);
func = callfunct;
func(value);
}
int main()
{
CallPrintfText(PrintfText);
return 0;
}
this code will be show"callfuct undeclared idenitifier"

Superku mean this : void CallPrintfText(void * callfuct,int value) { void func(int); func = callfunct; func(value); } its not the same name just correct it like this :
#include <acknex.h>
#include <default.c>
void PrintfText(int value)
{
printf("Hello World n%d!",value);
}
void CallPrintfText(void * callfunct,int value)
{
void func(int);
func = callfunct;
func(value);
}
int main()
{
CallPrintfText(PrintfText,50);
return 0;
}
