H Intmain (void) { Charstring [10]. Char * str1 = abcdefghi; Stpcpy (string, str1); Printf ( % s \ n , string); Return0; } The function name: strcat Work energy: string splicing functions Method: char * destin (char * source); Application: # include string. H # include stdio, h Intmain (void) { Chardestination [25]; A char * blank = c = c + + , * Borland = Borland; Strcpy (destination, Borland); Strcat (destination, blank); Strcat (destination, c); Printf ( % s \ n , destination); Return0; } Its a very real thing, and its a real thing The function name: STRCHR Work ability: find the first match of a given character in a string Method: char * STRCHR (char * STR, charc); Application: # include string. H # include stdio, h Intmain (void) { Charstring [15]. Char * PTR, c = r; Strcpy (string, Thisisastring); PTR = STRCHR (string, c); If (PTR) Printf ( Thecharacter % cisatposition: % d \ n , c, ptr-string); The else Printf ( Thecharacterwasnotfound \ n ); Return0; } The function name: STRCMP Work energy: crosstalk comparison Use: intstrcmp (char * str1, char * str2); Look at the Asic code, str1, str2, return value , 0; The two strings are equal, and they return 0 Application: # include string. H # include stdio, h Intmain (void) { Char * buf1 = aaa, * buf2 = BBB, * buf3 = CCC; Intptr; PTR = STRCMP (buf2 buf1); If (PTR 0) Printf ( buffer2isgreaterthanbuffer1 \ n ); The else Printf ( buffer2islessthanbuffer1 \
