The Park-Miller algorithm is a type of linear congruential generator (LCG) that is used to generate pseudo-random numbers. It is also called the minimal standard random number generator. The general formula of a random number generator (RNG) of this type is: X_{k+1} = g X(k) mod n where the modulus n is a prime number or a power of a prime number, the multiplier g is an element of high multiplicative order modulo n, and the seed X0 is co-prime to n. In this article, we will be using Park-Miller algorithm to generate 5 pseudo-random numbers using C++. Here is ... Read More

In this section we will see how to write a program in C that cannot be terminated by the Ctrl + C key.The Ctrl + C generates the keyboard interrupt, and it stops the execution of the current process. Here when we will press the Ctrl + C key, it will print a message then continues the execution. To use this functionality, we will use the signal handling technique in C. When the Ctrl + C is pressed it generates SIGINT signal. There are some other signals and their functionalities in the following list.SignalDescriptionSIGABRTIndicates Abnormal terminationSIGFPE Indicates floating point exceptionSIGILL Indicates invalid ...

Let us see how to write a C program in which we can print the text “Hello World” without using any semicolon.We can simply write the text by using the line printf(“Hello World”); in the main() function.But there is a semicolon at the end of the line. To avoid the semicolon, we can follow some trick. We can use the same printf() statement inside if condition. As the printf() statement returns the length of the text, so it is non zero value, so the if statement will be true. Thus the text will be written on screen.Example Code#include main() { ...

The probability density function (pdf) is a function that describes the relative likelihood for this random variable to take on a given value. It is also called as density of a continuous random variable. The probability of the random variable fall within a particular range of values is given by the integral of this variable's density over that range, So, it is given by the area under the density function but above the horizontal axis and between the lowest and greatest values of the range. Probability Distribution is based upon this probability density function. In this article, we will generate ... Read More

The middle-square method is one of the simplest methods of generating random numbers. This method will either begin repeatedly generating the same number or cycle to a previous number in the sequence and loop indefinitely. For a generator of n-digit random numbers, the period can be no longer than the specified n(number of digits). If the middle n digits are all zeroes, the generator then generates zeroes forever. In this article, we will implement a C++ program to generate ten 4-digits random number using the middle-square method. Steps for Middle-Square Random Number Generation The steps for generating random numbers ... Read More

Here we will see how to write a C program that can print numbers from 1 to 100 without using any kind of loops.This problem can be solved using the recursion. We will create a function that will be called recursively. As we know that a recursive function has basically two sections. The base case and the recursive call and other operation. In this function the base case is the argument n is greater than 1. Until it reaches 1, the function will be called recursively. Now at the end it will print the value of n. Thus the entire ...

In this section we will see how to check whether a number is odd or even without using any kind of conditional statements like (=, ==).We can easily check the odd or even by using the conditional statements. We can divide the number by 2, then check whether the remainder is 0 or not. if 0, then it is even. Otherwise we can perform AND operation with the number and 1. If the answer is 0, then it is even, otherwise odd.Here no conditional statements can be used. We will see two different methods to check the odd or even.Method ... Read More

The calculation of the sum of the digits of a number in a single statement means that only one line of code will be doing the addition operation. The addition operation should not extend more than one statement. In this article, we have a number and our task is to calculate the sum of the digits of the number in a single statement in c. Here is a list of approaches: Using for Loop Using Recursive Function Using for Loop This approach uses a for loop to calculate the ... Read More

The Linear Congruential Generator (LCG) is a very simple technique to generate a sequence of numbers that looks like random numbers but is actually determined. It is one of the reasons to call it a pseudo-random number. The Linear Congruential Generator (LCG) technique generates a random number based on the previous number and uses a linear recurrence to generate the sequence of random numbers. In this article, we have set an initial value of Xn and defined the value of the constants. Our task is to generate pseudo-random numbers using the linear congruential generator in C++. Formula of Linear ... Read More

Printing numbers from 1 to N is an easy task that can be achieved using loops, but to print numbers from one to N without using a semicolon is a tricky question. We will discuss two different methods to solve this question using iteration and recursion approaches. In this article, our task is to print numbers from 1 to 'n' and we don't have to use a semicolon. The approaches are listed below: Using Iteration Using Recursion Using Iteration This approach uses the iterative approach, where we have used the while loop to print the numbers from 1 to N. The num
