Initializing a pointer to point to a character in a string using the pointer pointing to the string

Question

int isPurePalindrome(const char *sentence){ 
int i;     
if (sentence="")     
return 0; 
char *begin; char *end; i=strlen(sentence);//i is now the length of sentence string 
*begin= &sentence(0); 
*end=&sentence[i-1];

I'm using dev c++. Im trying to initialize pointer "begin" to point to the first character in the string "sentence", but it keeps giving me an error that "assignment makes integer from pointer without a cast." "*sentence" points to the string entered by the user in the main. ispalindrome is a function im writing. its suppose to return a 0 if the sentence entered in main is a NULL.

Answer 1

There are a few issues with your code:

if (sentence="") return 0; 

should be

if (strcmp(sentence,"")==0) return 0;

---

char *begin; char *end;

should be

const char *begin; const char *end;

---

*begin= &sentence(0); 

should be

begin = &sentence[0];

---

*end=&sentence[i-1];

should be

end = &sentence[i-1];

Answer 2

There are a bunch of problems in your code, but the one causing that error message is that you're dereferencing when you don't need to be. You want:

begin = &sentence[0];
end = &sentence[i-1];

Answer 3

begin = &sentence[0];
end = &sentence[i - 1];

This will solve your problem..

Answer 4

You should write [] insted of () in

 *begin= &sentence(0); 

you should caste sentence to (char*) before assigning it to begin and end.

*begin =  ((char*)sentence)[0];

*end =  ((char*)sentence)[i -1];
