error in C

[appy]

hello everyone, i have a problem in C . in my program i use "strcmp" for compare word in sentance(for knowing is word in sentance or not) but i have an error:"strcmp" can not convert 1 parametr from char* to const char, i don,t understand this error,please help me!

my structure is:

char *sent[5],word[5];
if(strcmp(*sent[5],word[5])==0)
printf("the word found.");

strcmp syntax is:

strcmp(const char *s1,const char *s2) and your type is same as **sent which is same as sent[][],so
instead use it like:

strcmp(sent,wor d)

my structure is:

char *sent[5],word[5];
if(strcmp(*sent[5],word[5])==0)
  printf("the word found.");
 

strcmp syntax is:

strcmp(const char *s1,const char *s2) and your type is same as **sent which is same as sent[][],so
instead use it like:

strcmp(sent,wor d)

Well, not exactly. **sent is not "the same as" sent[][].

char *sent[5] is an array of 5 char pointers.
char word[5] is an array of 5 chars.

However, the prototype Savage gave is correct.

If you are using word to store a c-string and you are using sent to store an array of 5 c-strings then you would have to change it so that strcmp will receive a char const * or a char * (which the language will automatically convert to const). So if you compare the 0th c-string pointed at by sent to the c-string stored in word, you would use strcmp(sent[0], word).

The array will auto degrade to a pointer when used like this.

NOTE: You have not assigned the 5 pointers in sent, they are pointing at random memory locations. Also, word is not initialised either so its values are also indeterminate.
