unsafe_store!
unsafe_store!(p::Ptr{T},x,i::Integer)
Store a value of type T to the address of the ith element (1-indexed) starting at p. This is equivalent to the C expression p[i-1] = x.
The unsafe prefix on this function indicates that no validation is performed on the pointer p to ensure that it is valid. Incorrect usage may corrupt or segfault your program, in the same manner as C.

unsafe_store!(p::Ptr{T}, x, i::Integer)
Store a value of type `T` to the address of the ith element (1-indexed) starting at `p`.

The `unsafe` prefix on this function indicates that no validation is performed on the pointer `p` to ensure that it is valid.

julia> unsafe_store!(cstr, 'J', 8)Note: The unsafe_store! function should be used with caution as it bypasses the usual safety checks performed by Julia. It is primarily used when interacting with external libraries or low-level operations where manual memory management is required. Incorrect usage of unsafe_store! can lead to memory corruption or program crashes.
