Struck substring w/o strstr()

Hello! I have o proble in c

i have 3 stings on a struct (given from keyboard), and i want to find if a new string (from keyboard too) is a substring of the above 3 strings and the position tha it fount, without using strstr() function.

the struct have two values, the string and the string lenght

Hmm I understand the problem.. What is your code so far? :)

Also welcome to the forum.

I suppose you have already read the rules of this forum and the policy for the hw.

You could
a) write the code using strstr() to make sure everything works
b) write your own version of say my_strstr() to replace the library strstr() and make sure it still works.

Sorry for the delay!

Ive made something like that

Code:

---

for (k=0;k<size;k++){
for (j = 0; j <= (st[i].length - lenght2); ++j){
      for (i = 0; i < lenght2 && st[i].string[j] == input[i + j]; ++i);
 if (i >=  lenght2) {printf("\nMatch found at\n\n->[%d]\n->[%s]\n",j,input+j);}
  }

st[i].string[j] = the struct's strings
st[i].length =  the length of struct string
input = the substring
lenght2 = the substrings lenght
size = the st[i].string[j] size

I fount it, so dont bother. Thanx anyway!
