Explanation:
The pointer is the variable that will store the address of the other variable of the same datatype.
Following are the disadvantages of using a pointer.
1. Pointer sometimes causes a segmentation fault in the program.
2. Sometimes pointer leads to a memory leak.
3. A pointer variable is slower than normal variable.
4. Sometimes the program is crash if we using pointer because sufficient memory is not allocated during runtime.
5. If we using pointer it is difficult to find the error in the program.
