+## Задачи
+
+1. Да се състави функция sum(int a, int b), която приема две числа и връща като резултат сбора им.
+2. Да се напише функция isEven(int num), която връща дали дадено число е четно или не.
+3. а)Да се напише функция isPositive(int num), която връща дали дадено число е положително или не
+   b)Да се напише функция isNegative(int num), която връща дали дадено число е отрицателно или не.
+4. a)Напишете функция abs(int num), която връща като резултат абсолютната стойност на числото num.
+   b)Напишете функция fabs(double num), която връща като резултат абсолютната стойност на числото num.
+5. Напишете функция print(char S,int N), която извежда на екрана N-пъти символа S.
+6. Напишете функция isCapitalLetter(char S), която проверява дали даден символ е главна буква.
+   *Реализирайте функция checkSymbol(char S), която да проверява дали символът е буква.*
+7. a)Напишете функция, която проверява дали дадено число е в интервала [100;10000]
+   b)Напишете функция, която проверява дали дадено число е в даден интервал.
+ 
+8.Напишете функция pow(int num,unsigned N), която връща като резултат числото num повдигнато на степен N, където N е строго положително.
+9.Напишете функция calculate(nt a,int b, char action), където action може да бъде [+-*/%].
+  Програмата да връща като резултат съответното действие, а ако не се укаже символ да върне сбора на числата
+10.Напишете функция, askUser(int from, int to), която кара потребителя да въвежда числа докато не въведе число,
+  което да е в указания интервал, а като резултат връща въпросното число.
+
+11.Напишете програма, която по въведено число изкарва представянето му в двоична бройна система.
+   Реализирайте го чрез функция.
+12.Да се напише програма, която въвежда стойности на естествените числа a, b, c и d и намира и извежда най-големият общ делител
+   на числата a и b, след това на c и d и накрая на a, b, c и d.
+13.Напишете програма, която получава цяло естествено число в интервала [100;100000].
+   Програмата да изведе най - близкото число степен на двойката до това число.(тоест разликата на числата по абсолютна стойност да е минимална).
+   Входа да се валидира като при грешен ход да се дава възможност за нов опит.
+   Изкарайте отделните функционалности във функции.
