Use string constants in program generates a pointer to the character constants, when a string constants in an expression, the expression of the value is used by these characters stored address, rather than the characters themselves,

If there is any example, brothers

CodePudding user response:

For example:

 const char * STR="helloworld";//this assignment (=) the value of the expression is a string constant address assigned to the STR 

CodePudding user response:

Consider this:

 printf (" % s \ n ", "abcdef" + 1); 

It is the output of the
Bcdef
That means what?

Understand, thank you brother

Such as char * a="helloworld";
Printf (" % s ", a);//output helloworld
Printf (" % d ", a);//output is address
Mean for the helloworld this string specifies an address, this address is called a (is actually a string of Numbers, a just individual name), the other address is the address of the first character string h

Use % p print address;
, the name of this address is called a, the description is wrong, but a is a pointer, put "helloworld" the address of the string in a variable,
