Given a function uint16_t func(int16_t x) write a function callPassedFunc() that takes two arguments: • a pointer to func a int16_t and returns a uint16_t. A call to callPassedFunc() should have the same effect and return value as a call to func(), as in the example. Note that it should not matter what func() does. To test this question, write a few random function bodies for func(). For example: Test uint16_t func(int16_t x) { } return x/2; //Only an example could be anything. int16_t arg 10; uint16_t directRetVal= func(arg); uint16_t indirectRetVal callPassedFunc(&func, arg); printf("%d\n", directRetVal == indirectRetVal); Result 1

Question
Given a function
uint16_t func(int16_t x)
write a function callPassedFunc() that takes two arguments:
• a pointer to func
• a int16_t
and returns a uint16_t.
A call to callPassed Func() should have the same effect and return value as a call to func(), as in the example.
Note that it should not matter what func() does. To test this question, write a few random function bodies for
func().
For example:
Test
uint16_t func(int16_t x)
{
return x/2; //Only an example could be anything.
}
int16_t arg = 10;
uint16_t directRetVal= func(arg);
uint16_t indirect RetVal = callPassed Func(&func, arg);
printf("%d\n", directRetVal == indirectRetVal);
Result
