How to calculate sum of random numbers in between 0 to 100 using files in C Programming?
In this program, we are adding random numbers that are generated in between 0 and 100.After every runtime, the result of sum of random numbers is different, i.e., we get a different result for every execution.The logic we use to calculate the sum of random numbers in between 0 to 100 is −for(i = 0; i
Read MoreCalculate interest amount by using formula in C language
ProblemWrite a C program to calculate the deposited amount incremented after some years with interestSolutionThe formula for calculating interest is −M=((r/100) * t); A=P*exp(M);Where r= rate of interest t=no. of years P=amount to be deposited M=temporary variable A= Final amount after interestAlgorithmSTART Step 1: declare double variables Step 2: read amount to be deposited Step 3: read rate of interest Step 4: read years you want to deposit Step 5: Calculate final amount with interest I. ...

To multiply large numbers with all digits in the output, we can use mul.bigz function of gmp package. For example, if we have two vectors say x and y each containing numbers of large size then the multiplication of these numbers that will return all the digits of the multiplication can be done by using the command mul.bigz(x,y).Example1Loading gmp package and multiplying vectors containing large number values −library(gmp) x1
Read MoreHow to show values in boxplot in R?
The main values in a boxplot are minimum, first quartile, median, third quartile, and the maximum, and this group of values is also called five-number summary. Therefore, if we want to show values in boxplot then we can use text function and provide the five-number summary and labels with fivenum function as shown in the below examples.Example1x
Read MoreHow to create a horizontal boxplot in base R?
To create a horizontal boxplot in base R, we can set the horizontal argument inside boxplot function to TRUE. For example, if we have a vector called x then the horizontal histogram of that vector can be created by using the command boxplot(x,horizontal=TRUE).Example1x
Read MoreHow to create normal random variables with specific correlation between them in R?
To create normal random variables with specific correlation between them, we can use mvrnorm function of MASS package. For example, if we want to create two variables of size 10 with means equal to 2 and 4 and standard deviation of 0.5 then it can be done by using the command −mvrnorm(10,mu=c(2,4),Sigma=matrix(c(1,0.5,0.5,1),ncol=2),empirical=TRUE)Example1library(MASS) X
Read MoreHow to find prime factors of a number in R?
A prime number is the number that is only divisible by itself and one. These prime numbers can also divide other numbers hence they become a factor of those numbers. For example, 5 is a prime number and it also divides 20. To find the prime factors of a number, we can use primeFactors function of numbers package.Exampleslibrary(numbers)primeFactors(100)[1] 2 2 5 5primeFactors(1000)[1] 2 2 2 5 5 5 primeFactors(32547)[1] 3 19 571primeFactors(12354767)[1] 17 726751 primeFactors(21457)[1] 43 499primeFactors(99)[1] 3 3 11 primeFactors(365748)[1] 2 2 3 29 1051primeFactors(214687)[1] 11 29 673 primeFactors(3587497)[1] 3587497primeFactors(35874)[1] 2 3 3 1993 primeFactors(268713)[1] 3 3 73 409primeFactors(298473)[1] ...
Read MoreHow to subset a data.table object using a range of values in R?
To subset a data.table object using a range of values, we can use single square brackets and choose the range using %between%. For example, if we have a data.table object DT that contains a column x and the values in x ranges from 1 to 10 then we can subset DT for values between 3 to 8 by using the command DT[DT$x %between% c(3,8)].Example1Loading data.table package and creating a data.table object −library(data.table) x1
Read MoreHow to create empty bar plot in base R?
To create a bar plot in base R, we can use the function barplot and pass the vector or column of the data frame for which we want to create the bar plot but the bars created by using barplot by default has grey color. Therefore, if we want to create an empty bar plot then setting the color of bars to NA will make the plot an empty bar plot.Example1x
Read MoreWord Dictionary using Python Tkinter
In this article, we will create a GUI-based dictionary using PyDictionary and Tkinter Module.PyDictionary is a Python Module that helps to get meaning translations, antonyms and synonyms of words. It uses WordNet for getting meanings, Google for translations, and synonym.com for getting synonyms and antonyms. PyDictionary uses BeautifulSoup, Requests module as the dependencies.In order to create the application, we will first install these modules in our environment using pip install PyDictionaryAfter installing, we will create a tkinter frame and some other element.Example# Import Required Librares from tkinter import * from PyDictionary import PyDictionary # Create instances and objests dictionary ...
