When working with data visualization, plotting and saving a histogram on a local machine is a common task. This can be done using various functions provided by Python's Matplotlib, such as plt.savefig() and plt.hist(). The plt.hist is used function to create a histogram, by taking a list of data points. After the histogram is plotted we can save it, by using the plt.savefig() function. Steps to Plot, Save and Display a Histogram The steps included to plot and save the histogram are as follows. Configure ... Read More
To implement binary search without recursion, the program takes a sorted list and a key as input. It uses the Binary search method, which is an efficient way to find a specific item in a sorted list. It works by repeatedly dividing the list in half. This method works by first comparing the key with the middle element of the list. If the key matches the middle element, the search is successful, and the index is returned. If the key is less than the middle element, the search continues on the left subarray; if it's greater, the search shifts to ... Read More
A file is a collection of data stored in secondary memory, used for storing information that can be processed. Files allow data to be saved and retrieved later. They can store both programs and data, making file input and output operations crucial for reading from and writing to files. There are two types of files in C language which are as follows − Text file Binary File Text File Text files contain alphabets and numbers that are easily understood by humans. Errors in text files can be easily identified and ... Read More
In C programming language, generally, the special symbols have some special meaning. This language provides low-level access to the memory and it is identified for its performance and efficiency. The C language includes a character set of English alphabets(a-z, A-Z), digits(0-9), and specific meaning with special characters. Some special characters are operators, while combinations like "" are escape sequence. In C symbols are used to perform special operations. Some of the special symbols that are used in C programming are as follows − [] () {}, ; * = # Common Characters in C Programming Let’s understand their definitions, which ... Read More
A pointer is a variable that stores the address of another variable. The deceleration of a pointer is similar to that of a variable the only difference is while declaring a pointer we need to use "*". Following is the syntax to declare a pointer − type *variable_name; Similar to variables, pointers can be declared in different types. Following is an example − #Integer type pointer int *integer_pointer; #Character type pointer char *character_pointer; The following are the points to be noted − Pointers enable direct memory access and manipulation, which is crucial for ...

Loop control statements in C are designed to repeatedly execute operations until a specified condition is met. These Loops continue to run as long as the condition remains true. Loop control statements are used to repeat a set of statements. They are as follows − for loop while loop do-while loop For Loop in C The for loop in C allows us to repeat a set of statements a specified number of times. The for loop includes initialization, condition, and update statements within its syntax. It ... Read More
Type conversions change an expression from one data type to another. conversions can utilize many features of type hierarchies or data representation. Implicit type conversion Explicit type conversion Implicit Type Conversion Implicit type conversions, also known as type casting or type transformation, are automatic type conversions performed by the compiler. Most programming languages have compilers that handle type transformation automatically. When operands are of different data types, the compiler automatically performs implicit type conversions by converting the smaller data type into a larger one. int i, x; float f; double ... Read More
A file is a collection of data stored in secondary memory. The data is entered directly from the keyboard, files are used to store both information and programs. The following operations can be performed on files in the C language − Naming the file. Opening the file. Reading from the file. Writing into the file. Closing the file. File Naming and Opening The syntax for opening and naming file is as follows − FILE *File pointer; For ... Read More
To find difference between sums of two diagonals, we will be discussing two different approaches. We will calculate the sum of the elements present in the left and right diagonal, then we will subtract both sum values to get the difference. In this article we are having a square matrix, our task is to write a JavaScript program to find difference between sums of two diagonals. Example Input: Matrix: [[1, 2, 3], [4, 5, 6], [9, 8, 9]] Sum of left diagonal elements = 1+5+9 = 15 Sum of right diagonal elements = 3+5+9 ... Read More
In this article, we are going to check how we can remove duplicate elements from an array in C# using different approaches. What are Duplicate Elements in an Array? The elements which exist more than once in a given array are duplicate elements. In this problem, we are given an array, and we have to remove duplicate elements and print unique elements. Examples Input: array = {1, 1, 2, 3, 3, 4, 4, 4, 5, 5, 6, 6} Output:array = {1, 2, 3, 4, 5} Explanation: After removing the duplicate elements, the remaining elements are 1, 2, ... Read More
