C program to find sum of digits of a number using recursion.

C program to find sum of digits of a number using recursion. #include <stdio.h> int sumOfDigits(int num); int main() { int num, sum; printf("Enter a number: "); scanf("%d", &num); sum = sumOfDigits(num); printf("The sum of digits of %d is %d.\n", num, sum); return 0; } int sumOfDigits(int num) { if (num == 0) { return 0; } else { return (num % 10) + sumOfDigits(num / 10); } } Explanation : The program starts by including the standard input-output library stdio.h. The program defines a function sumOfDigits that takes an integer argument num and returns the sum of its digits. The function is defined using recursion. Inside the sumOfDigits function, there is an if statement that checks if the number num is equal to 0. If it is, the function returns 0 as the sum of digits. If num is n...

C program to check if a number is binary or not

C program to check if a number is binary or not #include <stdio.h> int isBinary(int num) { while (num != 0) { if (num % 10 > 1) { return 0; } num /= 10; } return 1; } int main() { int num; printf("Enter a number: "); scanf("%d", &num); if (isBinary(num)) { printf("%d is a binary number.\n", num); } else { printf("%d is not a binary number.\n", num); } return 0; } Explanation : This program defines a function isBinary that takes an integer num as input and returns 1 if num is a binary number, and 0 otherwise. The function checks each digit of the number by dividing it by 10 and checking if the remainder is greater than 1. If any digit is greater ...

C program to find greatest among three integers

C program to find the greatest among three integers: #include <stdio.h> int main() { int num1, num2, num3; printf("Enter three integers: "); scanf("%d %d %d", &num1, &num2, &num3); if(num1 > num2 && num1 > num3) { printf("%d is the greatest.", num1); } else if(num2 > num1 && num2 > num3) { printf("%d is the greatest.", num2); } else { printf("%d is the greatest.", num3); } return 0; } In this program, we first declare three integer variables num1, num2, and num3. We then prompt the user to enter three integers using printf() and read those integers using scanf(). Next, we use a series of if and else if statements to compare the three numbers and determine which is the greatest. We use the logical operators && and || ...

C program to check whether a number is palindrome or not

C to check whether a number is a palindrome or not using iteration: include <stdio.h> int main () { int num, reversedNum = 0 , remainder, originalNum; printf ( "Enter an integer: " ); scanf ( "%d" , &num); originalNum = num; // reverse the number while (num != 0 ) { remainder = num % 10 ; reversedNum = reversedNum * 10 + remainder; num /= 10 ; } // check if the number is palindrome or not if (originalNum == reversedNum) { printf ( "%d is a palindrome number.\n" , originalNum); } else { printf ( "%d is not a palindrome number.\n" , originalNum); } return 0; } Explanation : We first take an integer as input from the user using scanf . We then store the original number in a separate variable called originalNum . We use a while loop to reverse the input number. In each iteration, we get the remainder of the number when divided by 10 using the modulus operator (%). We then add ...

C program for Fibonacci series

C program to print fibonacci series using iteration #include <stdio.h> int main() { int n, i, fib0 = 0, fib1 = 1, fib; printf("Enter the number of terms: "); scanf("%d", &n); printf("Fibonacci Series: "); for (i = 1; i <= n; i++) { printf("%d ", fib0); fib = fib0 + fib1; fib0 = fib1; fib1 = fib; } return 0; } Explanation : * The program first prompts the user to enter the number of terms in the Fibonacci series. * It initializes variables fib0 and fib1 to the first two terms of the series. * The for loop is used to iterate from 1 to n, and in each iteration, it prints the value of fib0, which is the current term of the series. * The fib variable is used to calculate the next term of the series by adding fib0 and fib1. * Then fib0 is updated to the value of fib1, and fib1 is upd...

Data science: Tidy data

Data is an essential aspect of any data science project. As a data scientist, you'll spend a significant amount of time gathering and cleaning data to ensure it's suitable for analysis. Tidy data is a crucial concept in data science that can make your data analysis more straightforward and efficient. In this blog post, we'll take a closer look at what tidy data is and why it's important in data science. What is Tidy Data? Tidy data is a structured format for organizing data in a way that makes it easy to analyze. It was introduced by Hadley Wickham, a prominent statistician and data scientist, in his 2014 paper, "Tidy Data." In this paper, Wickham defined tidy data as a dataset that meets the following criteria: * Each variable has its column. * Each observation has its row. * Each value has its cell. In other words, tidy data is a way of organizing data in a tabular format where each variable is a column, each observation is a row, and each value is in its ow...

Data wrangling in Data science

Data wrangling is the process of cleaning, transforming, and preparing raw data for analysis. It is an important step in data science because raw data often contains errors, inconsistencies, or missing values that need to be addressed before meaningful insights can be derived. In this blog post, we will explore the importance of data wrangling in data science, its key components, and some best practices for successful data wrangling. Why is Data Wrangling important in Data Science? Data wrangling is critical in data science because raw data is often messy, incomplete, or inaccurate. Without proper data wrangling, data scientists may draw incorrect or incomplete conclusions, leading to poor decision-making. Moreover, the process of data wrangling can take up to 80% of a data scientist's time, highlighting its importance in the overall data analysis process. Key Components of Data Wrangling Data wrangling involves several key components, including data cleaning, data transformation, ...

Data Science : Grammar of Graphics

In data science, one of the most important steps is to visualize the data. Visualization helps to understand the data better, find patterns, and make informed decisions. The grammar of graphics is a framework for building visualizations that was introduced by Leland Wilkinson in 1999. This framework provides a systematic and comprehensive approach to creating graphs, which can be applied across a wide range of data types and data sources. The grammar of graphics is based on the idea of breaking down a visualization into a series of components, or layers, each of which can be customized and combined to produce a final graph. The components of a graph can be thought of as building blocks that are combined to create the final output. These components include things like the data itself, the aesthetic mapping of variables to visual properties, and the various layers that are added to the graph. The components of a graph can be broken down into the following elements: Data : This is the inf...
