C Programming: Modifying String Literals - Segmentation Fault

This code will result in a segmentation fault or undefined behavior.

The variable 'p' is a pointer to a string literal 'hello'. String literals are stored in read-only memory, which means that attempting to modify them will result in a segmentation fault or undefined behavior.

In this code, the statement 'p[0] = 'a'' attempts to modify the first character of the string literal, which is not allowed.

Therefore, the program may crash or produce unexpected results when executed.
