已知char s[]=”abcde”,*p=s,侧执行while(++p!=NULL);后*p的值为

在这个代码中,指针p指向字符串s的第一个字符'a',然后进入while循环。由于p不等于NULL,循环会一直执行下去。
在循环的每次迭代中,指针p会被递增,指向下一个字符,直到它指向字符串的结尾处的NULL字符。当p指向NULL字符时,循环条件不再成立,循环结束。
因此,执行完while循环后,指针p将指向字符串s的结尾处的NULL字符,即*p的值为NULL。

char *p="abcde";
As an AI language model, I can interpret the given statement as follows:
The statement declares a pointer variable named 'p' of type 'char' and assigns it the memory address of a string literal "abcde". The string "abcde" is a sequence of characters terminated by a null character '\0'.
The pointer variable 'p' points to the first character 'a' of the string literal "abcde". The pointer 'p' can be used to access the characters of the string literal.
Note that the string literal "abcde" is stored in read-only memory and cannot be modified through the pointer 'p'.
char*p="abcde";
This statement creates a pointer variable named p, which points to the first character of the string "abcde". The pointer variable p contains the memory address of the first character 'a'. The string "abcde" is stored in memory as a sequence of characters, with a null character ('\0') at the end to indicate the end of the string. The pointer p can be dereferenced using the * operator to access the value of the first character ('a').
