char_traits::lt
Tests whether one character is less than another.
static bool lt(
const char_type& _Ch1,
const char_type& _Ch2
);
Parameters
_Ch1
The first of two characters to be tested for less than._Ch2
The second of two characters to be tested for less than.
Return Value
true if the first character is less than the second character; otherwise false.
Example
// char_traits_lt.cpp
// compile with: /EHsc
#include <string>
#include <iostream>
int main( )
{
using namespace std;
char_traits<char>::char_type ch1 = 'x';
char_traits<char>::char_type ch2 = 'y';
char_traits<char>::char_type ch3 = 'z';
// Testing for less than
bool b1 = char_traits<char>::lt ( ch1 , ch2 );
if ( b1 )
cout << "The character ch1 is less than "
<< "the character ch2." << endl;
else
cout << "The character ch1 is not less "
<< "than the character ch2." << endl;
// An equivalent and alternatively test procedure
if ( ch3 < ch2 )
cout << "The character ch3 is less than "
<< "the character ch2." << endl;
else
cout << "The character ch3 is not less "
<< "than the character ch2." << endl;
}
The character ch1 is less than the character ch2.
The character ch3 is not less than the character ch2.
