Using pointer in C programming has following disadvantages: If pointers are referenced with incorrect values, then it affects the whole program. Memory leak occurs if dynamically allocated memory is not freed. Segmentation fault can occur due to uninitialized pointer. ...
tool, sometimes code get crashes due to improper use of pointers. If you do not use the pointers in a proper way, the pointer can become a curse and it can create a very crucial issue (segmentation fault or bus error). So let’s see the different states of pointers in C programming....
