Additional collection of problems with solutions
This page contains all of the tasks on the topics lessons, posted on our website. К каждой задаче прилагается наш вариант решения. Постарайтесь всё же решать их самостоятельно и только потом сравнивать наш исходный код со своим. “Хочешь научиться программировать – программируй”!
Больше практических заданий с решениями найдёте here.
Рекомендуем посетить Сайт для юных программистов – где вы найдете уроки по различным языкам программирования (в том числе для детей), 3D-моделированию, Linux и др.

Website purposely breaks my code
Can someone do this?) Or at least give me a hint))
Standard data types.
Given an integer Y – year, lying in the range 1970–2100; integer M –
month, lying in the range 1–12; integer D – current date, lying in
range 1–31. Determine the number of seconds that have passed since 1 January 1970
g. before the start of the specified date.
#include
using namespace std;
int main ()
{
int YMax,YMin,D,M,S,H,Mi;
YMin=1970;
YMax=2100;
M=12;
D=31;
H=60;
Mi=60;
S=60;
S=(YMax-YMin)*M*D*H*Mi*S;
cout<<S<<" seconds"<<endl;
return 0;

Develop a library of functions to perform operations with binary
wood. There should be a function of adding a tree node,
removal unit, search and analysis of the need for balancing.
And you can do this?)
I don't know why, but it was not published, put it after #include
May luck favor you)
help me please, 2 I've been sitting here racking my brain all day
“The field of the chess board is determined by a pair of natural numbers, each of which is no more than 8: First number – vertical number (when counting from left to right), second – horizontal number (when counting from bottom to top). Given natural numbers a, b, c, d NO more 8. On field a, b placed king, does it threaten field c, d.”
