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:
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
The characters A, E, I, O, U are known as vowels. The remaining 21 characters of English alphabets are known as consonants.
A character is said to be in uppercase if it is in capital letter and it is said to be in lowercase if it is in small letter. C program to check whether an entered character is in uppercase of lowercase is shown below.
A palindrome number is a number whose reverse is the original number. Some examples of palindrome number are: 121, 12321, 515, etc. C program to check whether the number is palindrome or not is shown below.
A quadratic equation is an equation of the form ax2 + bx + c = 0 where a, b and c are constants.
And the formula to calculate the roots of the quadratic equation is:
C program to find the roots of a quadratic equation is shown below.
An integer that can be exactly divided by 2 is known as an even number. An integer that cannot be exactly divided by 2 is known as an odd number. In other words, a digit that contains 0, 2, 4, 6 or 8 as its last digit is known as even number.
