str1==str2 returns 0;

str1<str2 returns -1;

Program example: Compare the sizes of string buf1 and string buf2 and output the result

 #include<string.h>#include<stdio.h>intmain(void){char*buf1=WWW.DOTCPP.COM,*buf2=www.dotcpp.com;intptr=stricmp(buf2,buf1);if(ptr >0){printf(buffer2isgreaterthanbuffer1n);}if(ptr<0){printf(buffer2islessthanbuffer1n);}if(ptr==0){printf(buffer2equalsbuffer1n);}return0;}

Running results:

 buffer2equalsbuffer1
