+Никола Светославов - task1
+
+## Задачи
+1.Напишете програма, която пита потребителя за името му, след което отпечатва "Hello, <име>"
+
+2.Напишете програма, която подканя потребителя да въведе дължините на двете страни на правоъгълник
+  **като му извежда съобщение, например "Please enter the length of the first side:"**
+  Програмата да изведе периметърът и лицето на този правоъгълник.
+  **Страните може да не са цели числа!**
+
+3.Напишете програма, която взима две числа от стандартния вход и извежда *true* ако първото е по - малко от второто
+  и *false* в противен случай.
+
+4.Напишете програма, която приема от входа две двойки реални числа, отговарящи на две точки в равнината.
+  Да се отпечата растоянието между точките закръглено до 2-рия знак след десетичната запетая.
+  **Потърсете математическата формула в интернет ако не я знаете!**
+
+БОНУС:Напишете програма която приема номер на кредитна карта(16 цифри).
+      Програмата да изведе същият този номер, но със скрити първите 12 цифри (XXXXXXXXXXXX1234).
+БОНУС:**Направете го без да записвате X-ове променлива и без да правите ```cout<<"XXXXXXXXXXXX"``` :)**
