Depending on the number of operands and function performed, the C++ operators can be classified into various categories. These include arithmetic operators, relational operators, logical operators,’ the conditional operator, assignment operators, bitwise operators and other ...
The order of the operators and their implementations is decided by the query optimizer using a combination of query transformations and physical optimization techniques. While the display is commonly shown in a tabular format, the plan is in fact tree-shaped. For example, consider the following ...

Using Loops in Programming In most of the programming languages, three looping structures 'for', 'while', and 'do-while' are used to perform the statements that need to be executed repetitively until a given condition is satisfied. For example, the 'for' loop can be implemented (in C) as...
