What is Wild pointer in C? Explain with an example.
A pointer which is not initialized is called a Wild Pointer. If the pointer is not initialized, it might point to a random location which might not even be a valid address range. The pointer shall be pointing to a garbage value.
Pointers must be initialized with NULL or assigned based on requirement. Let us consider below code to explain about Wild Pointer.
#include<stdio.h>
void main()
{
void main()
{
char *ptr;
}
}
In the above code, ptr is a wild pointer and can point to any arbitrary value.
#include<stdio.h>
void main()
{
void main()
{
char *ptr;
char p;
ptr = &p;
}
}
In the above code, ptr is no more a Wild pointer as it is assigned address of character variable p.
