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.

Here's the best way to find out if it's correct:

test it.

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
