strnicmp,strncmpi

原型：extern int strnicmp(char *s1,char * s2，int n); 用法：#include <string.h> 功能：比較字串s1和s2的前n個字元但不區分大小寫。 說明：strncmpi是到strnicmp的宏定義 當s1<s2時，傳回值<0 當s1=s2時，傳回值=0 當s1>s2時，傳回值>0 舉例： // strnicmp.c #include <syslib.h> #include <string.h> main() { char *s1="Hello, Programmers!"; char *s2="Hello, programmers!"; int r; clrscr(); r=strnicmp(s1,s2,strlen(s1)); if(!r) printf("s1 and s2 are identical"); else if(r<0) printf("s1 less than s2"); else printf("s1 greater than s2"); getchar(); return 0; }
