Mathematical and Text operators Operator Definition  Example  Result  ^  Exponent (power of)  5 ^ 2  25  *  Multiply  6 * 5  30  /  Divide  100 / 4  25  +  Add  6 + 4  10  -  Subtract  10 - 5  5  Mod  Remainder of division  25 Mod 7  4  \  Integer division  25 \ 9  2  &  String concatenation  "Usama" & " " & "Hafeez"  "Usama Hafeez"  Note that the order of operators is determined by the usual rules in programming. When a statement includes multiple operations the order of operations is: Parentheses ( ), ^, *, /, \, Mod, +, - Logical operators Operator  Definition  Example  Result  =  Equal to  12 = 15  False  >  Greater than  15 > 11  True  <  Less than  15 < 7  False  >=  Greater or eq...

Programing Is All about Reusability ,efficiency ,accuracy,precious,intelligence Of Example in Past Enterprises We were manged and document our accounts in ledger book but can we calculate and Analyze 10 Years of accounts or get lose and profits In average time? Thats why he Put Computers in our office and store or account information database use software to Analyze ,Calculate and managed there Account and make there data  Reusable  , faster and accurate . Evolution Of Programing Technologies is basically is a evolution of Reusability in Past Era of Programing Languages We Try to make Reusable Things in our program faster. 1 Structured programming c, Pascal Methods Reusability 2 Object Oriented Programming c++, Java, VB.NET, C# Objects Reusability 3- Component Oriented Programming c# collection of Objects Reusability 4- Service Oriented Programming (Azure,Cloud) Applications Reusability To Making Our Programming languages Object Oriented Fasting and Standard...
