为什么要打印完整的字符数组而不是第一个字符？

Question

This is the source code

char target[80]="hello", *tar;
tar=⌖
printf("%s",tar);  //printing hello

tar is getting the address of target[0] then why it is printing the whole character array.

Answer 1

when u say %s and specify a starting memory(or any intermediate) of the string it gets printed till it encounters '\\0' character.

consider

    char *name = "Hello";

will be stored internally as Hello\\0

so if u need a single character go for %c.

Answer 2

使用％c打印单个字符，使用％s打印字符串。

Answer 3

C strings are null terminated. When you pass the address of the first character in an array of characters representing a string to printf and tell it to format the output as a string using %s , it will print all of the characters beginning at the address of the first character until a null (NUL) character, '\\0' , is reached.

Answer 4

%s indicates printing characters between the character 'tar' points to and next '\\0' .

printf("%c",*tar);

will print what you need.
