(sort i lambda) a to wszystko w metodzie. » 2014-12-07 14:06:24 Witam, próbuję użyć sortowania w raz z lambdą w metodzie dla pewnej klasy. #include <iostream>
#include <algorithm>
using namespace std;
class klasa {
public:
int sortuj() {
int a[ 10 ] = { 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 };
sort( a, & a[ 10 ],[]( int x, int y ) { return x < y; } );
for( int i = 0; i < 10; i++ ) { printf( "%i ", a[ i ] ); }
printf( "\n" );
}
};
int main( int argc, char ** argv ) {
klasa nowy;
nowy.sortuj();
return 0;
}
