hello everyone, in this code, I got an error for char variable, does anybody know the reason? #include <iostream> using namespace std; int main() { char a = "b"; int e = 2.71; cout << a << e << endl; return 0; }

what error do you have?

it's solved, thank you 🙏

You can't initialise decimal values to integer type .you must use float or double but use float it should be better

The error was assigning const char* to char. It should be 'b'. You can assign float to int, most compilers will warn you though.

Hey wassup

I want mix std::thread with Qt how I can do that I try google bit don't find any info. Any help ?

However QT provides own thread. QThread

1 std 2 boost 3 Qt.

#include<studio.h> #include<iostream> using namespace std; int main() { cout << "Hello friends"; return 0; }

no need of stdio.h

can we search in pairs of pairs : pair< pair<int,int>, bool> pp; Like this - pair<int,int> p; if(i==0 || j==0) { p = make_pair(i,j); pp = make_pair(p,true); } else if (pp(i-1,j) == true || pp(i,j-1)==true) { p = make_pair(i,j); pp = make_pair(p,true); }

You probably want to use a data structure instead, where you can keep things and search things. I think what you are searching for is a map

Oh yeah thanks

Read about it and it's features. You don't need to invent the wheel

Given an array A on size N, you need to find the number of ordered pairs (i,j) such that i<j and A[i]>A[j].

Plz give me the solution
