Question

How can one compare a string from the middle (or some other point but not the start) to another string?
like i have a string
str1[]=”I am genius”;
now if i want to find a word in it how should i compare it with the word? for example the word is am.
Here is what i did.Its a bit stupid but works perfectly 😀

#include<stdio.h>

  #include<string.h>
  void print( char string[]);
  int  main()
{
  int i;
  char string1[20];
  printf("Enter a string:");
  gets(string1);
  print(string1);
  return 0;
  getch();
}
void print(char string[])
{
    int i,word=1,sum=0,x;

    for(i=0;    ;i++)
    {
    sum++;

    if(string[i]==' ')
    {
        printf("Word#%d:%d\n",word,sum-1);
        sum=0;
        word++;
    }/* if ends */
     if(string[i]=='\0')
     {    // program sai kaam karnay k liye ye code yahan bhi paste hona chahyey
        printf("Word#%d:%d\n",word,sum-1);
        sum=0;
        word++;
        break;
    }
    }/* for ends*/


}

Use strncmp():

strncmp( whereToFind + offsetToStartAt, patternToFind, patternLength );
