C program to calculate area of a circle using function.

C program to calculate area of a circle. In this example we will learn to calculate the area of a circle. Here in this program we will use 3.14 as the value of pi. The formula to calculate the area of a circle is: area= π r² Flowchart To Calculate the Area of a Circle: PROGRAM: #include <conio.h> #include <stdio.h> int main () { float radius , area ; printf ( "Enter the radius of the circle : " ); scanf ( "%f" ,& radius ); area = 3.14 * radius * radius ; printf ( "Area of the circle is : %.2f" , area ); ...

C Program to find the sum of the series 1^2+2^2+3^2+…..+n^2

C Program to find the sum of the series 1 2 +2 2 +3 2 +…..+n 2 Enter the end limit at the runtime. In this example, we calculate the sum of the above mentioned series till the end-limit entered by the user. We have used built-in function pow(x,y) to find the power of the given number. Here in the output we have entered the value of end-limit as number 7 which gives a sum of 140. PROGRAM #include <stdio.h> #include <math.h> #include <conio.h> void main () { int n,sum= 0 ,i; printf ( "Enter the end limit :" ); scanf ( " %d " ,&n); for (i= 1 ;i<=n;i++) { sum=sum+ pow (i, 2 ); } printf ( "Sum of the series is : %d " ,sum); ...

C Program to Calculate the Factorial of a number using Function

C Program to Calculate the Factorial of a number using Function. In this example, we will calculate the factorial of a number using function. Here we have used functions with Arguments and return value to perform this operation. We have declared a user-defined function fact which is called in the main function when printing the result. What is a Factorial of a Number? The factorial of a number is the product of all positive integers less than, equal to n. Factorial is denoted by the symbol '!'. Formula of factorial is n!=n x (n-1)! For example: 6!= 6 x 5 x 4 x 3 x 2 x1 = 720 PROGRAM TO CALCULATE THE FACTORIAL OF A NUMBER USING FUNCTION #include <stdio.h> #include <conio.h> int fact ( int ); void main () { int n ; printf ( "Enter the number : " ); scanf ( " %d " ,& n ); ...

C Program to input Values in a 2x2 square matrix and display the value

C Program to input Values in a 2x2 square matrix and display the value In this example, we will accept values from the user in a 2x2 square and matrix and then it is displayed. To solve this problem we must know what is matrices and arrays. What are Arrays? An array is a data structure for storing more than one data member of similar data type. Array can be of following types: One-dimensional Array Two-dimensional Array Multi-dimensional Array In Array we must always initialize values. PROGRAM #include <stdio.h> #include <conio.h> int main () { int a [ 2 ][ 2 ], i , j ; printf ( "Enter the values of the matrix:" ); for ( i = 0 ; i < 2 ; i ++) { for ( j = 0 ; j < 2 ...

C Program to Generate and Print Fibonacci series upto a given inputted number

C Program to Generate and Print Fibonacci series upto a given inputted number In this example, we will generate and print fibonacci series upto a the upper limit entered by the user. To solve this problem we should have a proper concept on Fibonacci series and while loop. What is a Fibonacci Series? Fibonacci series is the sum of the two preceding numbers, starting from 0 and 1. For Example: 0,1,1,2,3,5,8,13,....,etc PROGRAM #include <stdio.h> #include <conio.h> void main () { int n , x1 , x2 , x3 = 0 ; printf ( "Enter the limit upto which fibonacci series to be generated : " ); scanf ( " %d " ,& n ); x1 = 0 ; x2 = 1 ; printf ( " %d \t %d " , x1 , x2 ); x3 = x1 + x2 ; ...
