C Program to Display Patterns
The main thing required in creating a pattern in C is understanding how to use nested loops properly and knowing how the characters in pattern changes.
Here are a few examples to increase your understanding of patterns.
C Examples
C Program to Display Prime Numbers Between Two Numbers
A prime number is the number which can be exactly divided by only 1 and the number itself. For example, 5 can only be exactly divided by 1 and the number itself, so 5 is a prime number. But 8 can be divided by 1, 2, 4 and 8 so it is not a prime number but a composite number. To find and display all prime numbers between 10 and 100, nested loop is to be used. The outer loop runs from 10 to 100 and the inner loop checks whether the number is prime or not.
C Program to Display Sum of Some Series
There are different types of series in mathematics which can be solved easily in C programming. This section deals with finding sum of following types of series in C program.
C Program to Check Whether a Number is Prime or Composite
A prime number is the number which can be exactly divided by only 1 and the number itself. For example, 11 can only be exactly divided by 1 and the number itself, so 11 is a prime number. But 14 can be divided by 1, 2, 7 and 14 so it is not a prime number but a composite number.
C program to check whether a number is prime or composite is shown below.
C Program to Find Factorial of a Number
A factorial of a number can be defined as the multiplication of the number itself and its descending natural numbers. Factorial is denoted by ‘!’ symbol. e.g. the factorial of 5 is
5! = 5 x 4 x 3 x 2 x 1 = 120
The factorial of 1 is
1! = 1
C program to find the factorial of a number is shown below.
C Program to Find Largest and Smallest Number among N Numbers
C program to find the largest and smallest number among N numbers entered by the user is shown below
C Program to Print the Fibonacci series
Fibonacci series is the series of numbers which is found by adding the two numbers before it. For example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 …
C program to display Fibonacci series is as follows.
C Program to Check Prime Number
Prime numbers are those natural numbers which has exactly two factors : 1 and itself. If a number has factors more than two, they are composite. 1 and 0 are neither prime nor composite. C program to determine if a given number is prime or not is shown below:
C Program to Calculate Power of a Number
The power of a number can be defined as how many times the number is multiplied with itself. For example:
93= 9 X 9 X 9 = 729 25= 2 X 2 X 2 X 2 X 2 = 32
This can be written in the form xn. So, in this program we ask the user to input the value of x and n.
C Program to Find the Sum of First N Natural Numbers
Natural numbers are the whole numbers starting from 1. They are 1, 2, 3, 4, ….. and so on.
This program asks the user to input the number of terms whose sum the user would like to find.
