Something tells me you're looking for std::abs.

Standard algorithm std::remove_if can remove elements of a sequence by condition.
If you mean an array then you can not remove elements from an array but you can substitute them for some predefined values. In this case you should use std::remove_if together with std::fill.

For example,

1
2
3
4
 
int a[] = { 1, -2, -3, 4, 5, 6, -7, 8, -9 };

std::fill( std::remove_if( std::begin( a ), std::end( a ), 
                                     [] ( int x ) { return ( x < 0 ); } ), std::end( a ), 0 );

any other easy coding??

It is not clear what are your "negative integeres in integers".:)

for example : 60 59 -76 -90 53 99 -28
the question what coding that i can removes this negatives values without changing the order?

And what is it? Where are these values stored? If they are stored in array you can use the code I showed above.

Your code is incorrect because the value of class member item is undefined.
