char *str = NULL; // Implicit conversion from void * to char * int i = NULL; // OK, but `i` is not pointer type 2️⃣ Function calling ambiguity void func(int) {} void func(int*){} void func(bool){} func(NULL); // Which one to call? Compilation produces the following ...
A void pointer, also known as a generic pointer, is a pointer that is not associated with any specific data type, making it suitable for pointing to any type of data. In other words, avoid pointercan point to an integer, a character, a string, or any other data type. This flexibility...

In C++, what are the differences between static variables and dynamic variables? 1. Mark the following statements as true or false: a. In C++, "pointer" is a reserved word. b. In C++, pointer variables are declared using the word "pointer". c. The statement "delete p;...
I am struggling to understand what is the purpose of pointers and references? why do we need them? How are they different from one another? Any practical use of pointers and references would be helpful. Thanks c++pointerscppreferences
Arrays: When there is a need to use many variables, then there is a big problem because we will Conflict with the name of variables. So that in this situation where we want to Operate on many numbers, we can use array. The Number of Variables also increases the complexity of the Progra...
When you select the start and end values for the stack pointer in the RTOS tool window, it opens in the memory window. Added thread awareness for device targets to the call stack window. Users can now select a pin icon next to peripherals, registers, or fields to pin them the top of ...
For example, by calling an error-handling function if index is invalid. extern int error_handler(const char *message); /* *a : Pointer to an array of signed integers n : Number of elements in the array index : The index of the element within the array to return */ int func(int *...
