admin The C++ needs logical operators to control the flow of the program. The expressions involving logical operators evaluate to boolean value – true or false. Then the program makes decisions based on the outcome. There are three types of logical operators. Logical Operators Description && Logical AND || Logical OR ! Not Note that there … Read more
The assignment operators assign new values to the variable. The variable may already be holding a value ,but the assignment will change the current value to a new one. It can appear anywhere within an expression, with the sole purpose of assigning the right-hand-side (RHS) value to the left-hand-side (LHS) value. Here is the list … Read more
Arithmetic operators carry basic arithmetic operations in a C++ program. These operators are used in simple mathematical expressions. They are also known as binary operators because each operator requires at least two operands. Here is a list of arithmetic operators. Arithmetic Operators Description + Addition – Subtraction * Multiplication / Division % Modulo The operators … Read more

In mathematics, there are many series whose sum is calculated using computer programs to reduces the effort of doing enormous computations. This example program computes the sum of series ( ). The user has to input the value of n. To write such programs you must be careful about two things – accuracy and type … Read more
This program is a demonstration of the use of C++ math header. Given 3 sides or angle values of a triangle, this program computes all 6 trigonometric ratios and print the result to the console. The trigonometric ratios are calculated using builtin function from math.h header file. Learn the basics of C programming before you … Read more
The C++ programming language offers different types of operators. These operators are used in expressions that evaluate to a single value. Sometimes the operator is used in decision making that changes the flow of the program. Here is the diagram that classifies C++ operators into different categories. Arithmetic Operators Operator Description + Addition operation – … Read more
Numbers can be represented using Integer data types in C++. But some numbers like real numbers cannot be stored like integers because there is a decimal part associated with the real numbers. C++ programming language has and data type to represent real numbers. A real number is declared using keyword – or . The main … Read more
Visual basic open a project in design view where you can modify project properties like project name and description, version information, and other similar attributes. Managing VB 6 projects is easier than you may think. The project tab in the visual basic standard toolbar contains project properties which allow us to change settings related to … Read more
