Why can't the output go right

[Irene-Ren]

#include
using namespace std;
bool b[105];
int main(){
int n,m,x,y;
cin>>n>>m;
b[0]=1;
for(int i=1;i<=n;i++){
cin>>x>>y;
for(int j=x+1;j<=y;j++) {
b[j]=1;

	}
**_cout<<b[i]<<" ";_**
}
int w=0;
for(int i=0;i<=m;++i)
	if(b[i]==0) w=1;
if(w)
	cout<<"NO"<<endl;
else
	cout<<"YES"<<endl;
return 0;	

}`

The bolded part is meant to be the testing row to see how the whole program works during compiling,it was expected to output the queue from 0 to n,however, it can only output a '1'.Please help if you know where the bug is,thanks!

The goal of the 'cout' testing code is not clear. Its output depends on how many teleports there are (represented by n), more specifically, it will out put b[1:n], but I think what you want is b[0:m].
