I wondered for a long time how to make different user-operators. For example write this x minEqual y instead of x = min(x, y)↵
↵
So recently I've done this, and decided to share it with you.↵
↵
↵
~~~~~↵
#include <bits/stdc++.h>↵
↵
using namespace std;↵
struct mineq_operator↵
{↵
int tempVal=1000;↵
inline mineq_operator operator<<(int& x)↵
{↵
this->tempVal = x;↵
return *this;↵
} inline mineq_operator operator>>(int& x)↵
{↵
x = min(x, tempVal);↵
return *this;↵
}↵
};↵
mineq_operator __me;↵
inline void operator<<(int& x, mineq_operator& b)↵
{↵
b.tempVal = x;↵
}↵
#define minEqual <<__me;__me>>↵
signed main()↵
{↵
int x = 3, y = 2;↵
y minEqual x;↵
cout << x << ' ' << y << endl;↵
}↵
~~~~~↵
↵
For use it like `x = min(x, y);` just write `y minEqual x`;↵
↵
And this in compressed format:↵
↵
~~~~~↵
#include <bits/stdc++.h>↵
↵
using namespace std;↵
struct mineq_operator {int tempVal=1000;inline mineq_operator operator<<(int& x) {this->tempVal = x;return *this;}inline mineq_operator operator>>(int& x) {x = min(x, tempVal);return *this;}};↵
mineq_operator __me; inline void operator<<(int& x, mineq_operator& b) {b.tempVal = x;}↵
#define minEqual <<__me;__me>>↵
signed main() {↵
int x = 3, y = 2;↵
y minEqual x;↵
cout << x << ' ' << y << endl;↵
}↵
