programtopia1 Constants In any programing language including C#, constants are values which are fixed and cannot be changed anytime during program execution. They can be of any data type. We can use const to make a variable constant. Example of some constants are:
In this program, the user is asked to enter any one of the operators +, -, *, / and also two operands. The operation chosen by the user is carried out on the two operands.
This C program displays the name of the day by asking the user to input a number. For example, if the user enters 1 then “SUNDAY” is displayed, if the user enters 2 then “MONDAY” is displayed and so on. The C program code to display the day name according to number you entered are as follows.
A year that has 366 days is called a leap year. A year can be checked whether a year is leap year or not by dividing the year by 4, 100 and 400. If a number is divisible by 4 but not by 100 then, it is a leap year. Also, if a number is divisible by 4, 100 and 400 then it is a leap year. Otherwise the year is not a leap year.
To find the largest among 3 numbers entered by the user in C programming, nested if can be used which is implemented in following program:
In any programing language including C#, variables are the memory space in computer where data can be stored. A variable in C# programming is defined by three main features: name, type and value (optional). Let us take an example: int var = 1; In above example, var is the name of variable, int is the type of variable var and 1 is the value stored in memory location.
Armstrong number is the number whose sum of cube of individual digits is the number itself. For example: 153, 407 etc. 153 = 13 + 53 + 33 // Armstrong Number Example: Source Code to Check Armstrong Number
Type Conversion is process of converting one data type into another data type. This help us choose most appropriate type for the variable. It is also known as type casting. It can be done in two ways:
Data type is a categorization of variable to define what type of data can be stored in that variable. In C#, declaration of a data type is compulsory. This helps compiler know what type of data will be stored in that variable. These data types can be categorized in following three types:
The characters A, E, I, O, U are known as vowels. The remaining 21 characters of English alphabets are known as consonants.
