What the&operator does is retrieve the lvalue (address) ofk, even thoughkis on the right hand side of the assignment operator '=', and copies that to the contents of our pointer ptr. Now, ptr is said to "point to"k. Bear with us now, there is only one more operator we need to ...
It may be noted that during its lifetime, a pointer variable need not always point to the same variable. We can manipulate the pointer itself so that it points to other variables. This is particularly useful while working with arrays. For example, the ++ operator increments the address stored...
Issues with NULL 1️⃣ Implicit conversion 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 on...
void add_one(int *x) { *x += 1; } This code takes a pointer to an integer (*x) and then increments the value by one. Here is a main function to exercise the code: C #include <stdio.h> int main(void) { int y = 2337; printf("y = %d\n", y); add_one(&y); print...

Therefore, it is recommended to write a good and safe program you should always initialize array elements with default values. Example Consider the program: #include<stdio.h>intmain(void){inta[5];intb[5]={0};intc[5]={0,0,0,0,0};inti;//for loop counter//printing all alements of ...
void oops(std::vector<std::string>& v) { set_name(v.front().c_str()); // ^^ } Here’s how to decode the error message: A“bound function” is An object, a dot, and a member function name, or A pointer, a->arrow, and a member function name. ...

Below is an example of code that creates a dangling pointer: #include<stdio.h>#include<stdlib.h>#include<string.h>2:voidmain(){char*name=(char*)malloc(20);execute some codefree(name);} Copy Line 5 declares a char type pointer "name" that points to a ...
