Using STRSTR function

One example of C:

 # include & lt; stdio.h> 
# include & lt; String. H> 

Void foundPos (char * dest, const char * subs, char * buf) 
{
Char * PCH. 
Int pos. 
Char tmpStr [10]. 

PCH=STRSTR (dest, subs); 
While (PCH!=NULL) {
Pos=PCH - dest; 
Sprintf (tmpStr, "% d", pos + 1); 
Strcat (buf, tmpStr); 
Strcat (buf, ""); 
PCH=STRSTR (PCH + 1, subs); 
} 
} 

Int main () 
{
Char STR []="abcbbbabc"; 
PCH char [100]={0}; 
Printf (" & the for 'ABC' in the \ "% s \ " n ", STR); 
FoundPos (STR, "ABC", PCH); 
Printf (" % s \ r \ n ", PCH); 
return 0; 
}
