Database functions -- string comparison -- case-insensitive

Header file: # include <string. h>

Define the function: int strcasecmp (const char * S1, const char * S2 );

Function Description: strcasecmp () is used to compare S1 and S2 strings. Differences in case are automatically ignored during comparison.

Return Value: If the S1 and S2 parameters are the same, 0 is returned. If the S1 length is greater than the S2 length, a value greater than 0 is returned. If the S1 length is smaller than the S2 length, a value smaller than 0 is returned.

# Include <string. h> # include <stdio. h> int main () {char * A = "abcdef"; char * B = "abcdef"; if (! Strcasecmp (a, B) printf ("% s = % s \ n", a, B); Return 0 ;}
