Thread: Is my main function correct?

I have to split(s,c,sl,sr)-splits a string s into two substrings sl and sr. Sl is the portion of the string to the left of c and sr is the portion following c. If the string does not contain c, sl is a copy of s and sr is empty string. This is a utility function called by other functions. It returns true if c is found in s, otherwise it returns false. S and c are input parameters, and sl and sr are output parameters. Assuming that all parameters are strings.

Code:

split(char s; char c; char sl; char sr) 
int main(void) 
{
   int i = 0; 
   char sl, sr, s, c;
   char *chptr, name, value;
   char sentence[15][80], a[10], b[100]; 

   printf("Please enter a URL."); 
   fgets(sentence, 80, stdin);
   for(chptr = sentence; *chptr != '\n'; chptr++);
   *chptr = '\0';

   while(i>7)
   { 
       sentence[i] = a[i]; 
       i++; 
   }

   if(strcmp(a[i], "http://"))
   { 
       exit(0);
   }

   while(sentence[i] != b[i])
   {
       sentence[i] = b[i]; 
       i++;
   }
   printf("The domain name:", b[i]);

I'm new to "C" programming so I don't know clearly what I'm doing.

Dear friend,
In your main function you are comparing the string using the following.
strcmp(a[i],"http://").
But the array 'a' is not having any value.
So if you run this program it will produce segmentation fault.

Code:

split(char s; char c; char sl; char sr)     // this is a syntax error. no return type missing semicolon
int main(void) 
{
   int i = 0; 
   char sl, sr, s, c;
   char *chptr, name, value;
   char sentence[15][80], a[10], b[100]; 

   printf("Please enter a URL."); 
   fgets(sentence, 80, stdin);              // there are 15 sentences  you have to choose one for input
   for(chptr = sentence; *chptr != '\n'; chptr++);
   *chptr = '\0';

   while(i>7)                               // this loop will either not be entered ( if i < 8 ) or it will loop forever
   { 
       sentence[i] = a[i];                  // you cannot assign a char to a string
       i++; 
   }

   if(strcmp(a[i], "http://"))              // you cannot compare a char and a string
   { 
       exit(0);
   }

   while(sentence[i] != b[i])               // you cannot compare a char and a string
   {
       sentence[i] = b[i];                  // you cannot assign a char to a string
       i++;
   }
   printf("The domain name:", b[i]);        // incorrect format string
