回答1:

strcmp

原型:extern int strcmp(char *s1,char * s2);

用法:#include

功能:比较字符串s1和s2。

说明:
当s1 当s1=s2时,返回值=0
当s1>s2时,返回值>0

举例:

// strcmp.c

#include
#include

main()
{
char *s1="Hello, Programmers!";
char *s2="Hello, programmers!";
int r;

clrscr();

r=strcmp(s1,s2);
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;
}
