I previously thought that you can “force” varibles in to a temporary struct by using {} to sort of “bind” them together. I used this a couple times before and they worked. But this time it didn’t work.

#include<bits/stdc++.h>
#include<windows.h>
using namespace std;
struct task{
    long long a,b;
};
map<task,bool>tasks;
long long lst[10012],sum[10012],sub[10012];
int main(){
    long long n,p,h,m;
    cin>>n>>p>>h>>m;
    for(int i=0;i<m;i++){
        long long ta,tb;
        cin>>ta>>tb;
        task[{ta,tb}]=true;
    }
    for(auto &t:tasks){
        task cur=t.first;
        sub[cur.a+1]--;
        sub[cur.b]++;
    }
    for(int i=1;i<=n;i++){
        sum[i]=sub[i]+sum[i-1];
        cout<<sum[i]<<endl;
    }
}

So to restate the question:
How to use {} characters to assign multiple varibles into a temperary struct and then use them in the [] of a map

I tried add “task” before the { character but it didn’t work
I tried using a temporary varible to solve this problem. it worked but didn’t achieve my goal of learning this new element of syntax.
