Question
In C, what is the result of declaring a pointer as int *ptr;
without initialization?
Solution
When you declare a pointer in C using int *ptr;
without initialization, the pointer ptr
is likely to point to some random memory location, which can be any location in the memory of your computer. This is because, in C, local variables are not initialized by default. This could potentially lead to undefined behavior if you try to access or manipulate the memory location that ptr
points to without properly initializing ptr
first. It's generally a good practice to initialize a pointer to NULL if you do not have a suitable address to assign to it at the time of declaration.
