strcmp
Syntax:
#include <cstring> int strcmp( const char *str1, const char *str2 );
The function strcmp() compares str1 and str2, then returns:
| Return value | Explanation |
|---|---|
| less than 0 | ''str1'' is less than ''str2'' |
| equal to 0 | ''str1'' is equal to ''str2'' |
| greater than 0 | ''str1'' is greater than ''str2'' |
For example:
printf( "Enter your name: " );
scanf( "%s", name );
if( strcmp( name, "Mary" ) == 0 ) {
printf( "Hello, Dr. Mary!\n" );
}
Note that if str1 or str2 are missing a null-termination character, then strcmp() may not produce valid results. For a similar (and safer) function that includes explicit bounds checking, see strncmp().
