C library function - strcoll()
Description
The C library function int strcoll(const char *str1, const char *str2) compares string str1 to str2. The result is dependent on the LC_COLLATE setting of the location.
Declaration
Following is the declaration for strcoll() function.
int strcoll(const char *str1, const char *str2)
Parameters
str1 − This is the first string to be compared.
str2 − This is the second string to be compared.
Return Value
This function return values that are as follows −
- if Return value < 0 then it indicates str1 is less than str2.
- if Return value > 0 then it indicates str2 is less than str1.
- if Return value = 0 then it indicates str1 is equal to str2.
Example
The following example shows the usage of strcoll() function.
#include <stdio.h> #include <string.h> int main () { char str1[15]; char str2[15]; int ret; strcpy(str1, "abc"); strcpy(str2, "ABC"); ret = strcoll(str1, str2); if(ret > 0) { printf("str1 is less than str2"); } else if(ret < 0) { printf("str2 is less than str1"); } else { printf("str1 is equal to str2"); } return(0); }
Let us compile and run the above program that will produce the following result −
str1 is less than str2
