Hello, Help Me Please With algorithm. I have a really hard task with C++.
Here's my txt files
Classes

2a monday 1 history 2 math 3 biology 4 x
2a tuesday 1 math 2 history 3 art 4 music
2a wednesday 1 biology 2 history
2a thursday 1 math 2 programming 3 art
2a friday 1 math 2 x
2b monday 1 math 2 biology 3 art 4 x
2b tuesday 1 art 2 math 3 biology 4 x
2b wednesday 1 biology 2 geography 3 music
2b thursday 1 histrory 2 math 3 art
2b friday 1 music 2 technology 3 art

Teachers (sport)
first number day second which lesson are the sport and last one if the have that lesson 1-yes 0-no.

Please don't keep spamming the forums with the same question.

Sorry!

[deividas717]

Why this question is the same? Earlier I ask to help me to READ a Classes file and now I need an algorithm

[MikeyBoy]

Oh, OK. Sorry.

So, it is possible to get help? :/ I have written this program, but it has a lot of errors... Here's my code http://pastebin.com/2cWAr2eA (ERROR start at 152 line :(

[norm b]

Stringing the operator== 's together is not doing what you expect because operator== returns a bool.

Simple example:

#include <iostream>

int main(){
	int x(42);
	int y(42);
	int z(42);
	if(x == y == z) 
		std::cout << "All are equal" << std::endl;
	else 
		std::cout << "Not equal" << std::endl;
}

Output:

Not equal

x == y evaluates to true(1) which is not equal to 42.

The reason you get an error is the compiler cannot evaluate bool == std::string.

main.cpp:152:62: error: invalid operands to binary expression ('int' and 'string'
(aka 'basic_string<char>'))
if( (p[i].ImtiDiena() == m[h].ImtiMokDiena() == t[v].ImtiTDienos() ) && (...

Ok I think i have fixed that problem

if((p[i].ImtiDiena() == m[h].ImtiSavDiena() == atoi(t[v].ImtiTDienos().c_str())) && (p[i].ImtiNr() == m[h].ImtiMokDiena()) && m[h].ImtiMokUzimtumas() == 0  &&  p[i].ImtiPamoka()=="x"){
					
				}

But is it correct?
