Are you talking about a managed array? Managed arrays are a reference type so it would pass in a reference to that array. static int Sqrt(int x) { if (x<0) throw new ArgumentOutOfRangeException(); int temp, y=0, b=0x8000, bshft=15, v=x; do { if (v>=(temp=(y<<1)+b<>=1)>0); return y; :omg:

cin and cout aren't class or object. They are both functions. we can use them without declaring because they have been declared in iostream.h -- modified at 2:53 Sunday 13th August, 2006 -- modified at 2:55 Sunday 13th August, 2006 I love this web

thnks to both of u for spending your valuable time to reply a simple question like this. Shamnar shamnar

The application attempted to write to an area of memory for which it either had no permission, or more likely an area of memory that is not writable. Debugging the application should help you by prviding a call stack. Darka [Xanya]

thank you.......... shamnar

finaly i did it. thanks for ur advices and clues u have given to me. but i made one more instruction. i am sending it along with this char* rmstr(char* searchstring, char* morphem) { char* tmp; char* resultstring = (char *) malloc(strlen(searchstring)); *resultstring = '\0'; while( ( tmp = strstr(searchstring, morphem))!='\0')// ) { int len=strlen(searchstring)-strlen(tmp); //...; char* result = (char *) malloc(len);//...; strncpy(result,searchstring,len);//...); searchstring = tmp+strlen(morphem);//(...); *(result+len) = '\0'; strcat(resultstring,result);//...); free (result); } if (searchstring!='\0') strcat(resultstring,searchstring); free (resultstring); return resultstring; } thanks for make me to study pointers. shamnar
