#include <string.h>int strncmp(const char *str1, const char *str2, size_t count);
The strncmp( ) function lexicographically compares not more than count characters from the two null-terminated strings and returns an integer based on the outcome, as shown here:
|
Value |
Meaning |
|---|---|
|
Less than zero |
str1 is less than str2 |
|
Zero |
str1 is equal to str2 |
|
Greater than zero |
str1 is greater than str2 |
If there are less than count characters in either string, the comparison ends when the first null is encountered.
