how to set a pointer to an offset in c
To set a pointer to an offset in C, you can use pointer arithmetic. Here is an example:
int array[5] = {1, 2, 3, 4, 5};
int *ptr = array; // Set the pointer to the start of the array
// Move the pointer to the desired offset
ptr = ptr + 2; // This will move the pointer two elements ahead
printf("Value at offset 2: %d\n", *ptr); // Prints the value at the offset 2
In the above code, ptr
is initially set to the start of the array
. By adding an offset to the pointer (ptr + 2
), we move the pointer two elements ahead in the array. The value at the desired offset can be accessed using the dereference operator (*ptr
). In this example, the value at offset 2 is printed using printf
.
Note: It's important to ensure that the offset you set for the pointer is within the bounds of the array to avoid undefined behavior.
