C Program for N-th term of Arithmetic Progression series
Given ‘a’ the First term, ‘d’ the common difference and ‘n’ for the number of terms in a series. The task is to find the nth term of the series.So, before discussing how to write a program for the problem first we should know what is Arithmetic Progression.Arithmetic progression or arithmetic sequence is a sequence of number where the difference between the two consecutive terms is same.Like we have first term i.e a =5, difference 1 and nth term we want to find should be 3. So, the series would be: 5, 6, 7 so the output must be 7.So, ...
Read MoreC Program to calculate the Round Trip Time (RTT)
Given an Url address of any website; the task is to calculate the round trip time of a website.Round Trip Time(RTT) is the total time or the length of a time which is taken to send a signal plus the time taken to receive the acknowledgement of that signal to be received. This time also consist of the propagation times between two points of a signal.An end user can determine his/her round trip time from an IP address by pinging that address.The Round Trip time’ result depends upon the following reasons −The Transmission medium.The presence of Interface in the circuit.Number ...
Read MoreC Program to Change RGB color model to HSV color model
Given RGB color range in form of integers; the task is to find its appropriate HSV color by converting the RGB color rangeWhat is RGB color modelRGB color model comprised of three colors Red, Green and Blue. RGB model is a color model which is widely used in the display technologies; it is an additive model in which we add these three colors of with different intensities to produce millions of different colors on a display device.What is HSV color model?HSV color model comprises Hue, Saturation, Value also known as HSB (Hue, Saturation, Brightness).HSV is alternative representation of RGB color ...
Read MoreC Program to convert a given number to words
Given a string consisting of numerical values, the task is to covert those given numbers in words.Like we have an input “361”; then the output should be in words i.e, ” Three hundred sixty one”. For the solution of the following problem we have to keep in mind the numbers and places it is in on like ones, tens, thousands etc.The code only support upto 4 digits numbers i.e., 0 to 9999. So the input should be from 0 to 9999.Let us consider 1, 111 so the places will be like −ExampleInput: “1234” Output: one thousand two hundred thirty four ...
Read MorePrinting all subsets of {1,2,3,…n} without using array or loop in C program
Given a positive integer n we have to print all the subsets of a set of {1, 2, 3, 4, … n} without using any array or loops.Like we have given any number say 3 s we have to print all the subset in the set {1, 2, 3} which would be {1 2 3}, {1 2}, {2 3}, {1 3}, {1}, {2}, {3} { }.But we have to do this without using any loop or an array. So, only the recursion is the possible way to solve this type of problem without using any array or a loop.ExampleInput: 3 ...
Read MoreBash program to check if the Number is a Prime or not
Bash also known as GNU bash is a command language and unix shell script is a command line interpreter for operating system. It was designed by Brian Fox and was a free software which replaced Bourne shell. It first released in 1989 and some became go to for login shell for linux based operating systems like macOS, Linux based softwares, etc.Prime number is a number that has only two factors i.e. the number itself and 1. For example, 2 , 3 , 5, 7 , 11 , 13 , 17 , 19 , 23 , 29….Here we are given a ...
Read Morebar() function in C graphics
bar() function is a C graphics function that is used to draw graphics in the C programming language. The graphics.h header contains functions that work for drawing graphics. The bar() function is also defined in the header file.Syntaxvoid bar(int left, int top, int right, int bottom );The bar() function is used to draw a bar ( of bar graph) which is a 2-dimensional figure. It is filled rectangular figure. The function takes four arguments that are the coordinates of (X, Y) coordinates of the top-left corner of the bar {left and top } and (X, Y) coordinates of the bottom-right ...
Read MoreBands in Radio frequency Spectrum in C program
Radio frequency (RF) is the oscillation of an A.C. current or an A.C. voltage or any other oscillating body in the frequency range of 20KHz to 300 GHz.Radio frequency spectrum of a device is the frequency range that the device can capture, process or repercate. Generally the frequency range is 20Hz to 20KHz.A band is a frequency range that is divided from very low frequency to extremely high frequency. These bands are small ranges of frequency that are used to provide small parts of the spectrum.Bands In Radio Frequency SpectrumFrequency Range is range of continuous that has an upper limit ...
Read MoreMCQ on Memory allocation and compilation process in C
Here we will see some MCQ questions on Memory Allocation and Compilation Processes.Question 1 − What will be the output of the following code − Live Demo#include #include int main() { union my_union { int i; float f; char c; }; union my_union* u; u = (union my_union*)malloc(sizeof(union my_union)); u->f = 20.60f; printf("%f", u->f); }Options −Garbage Value20.600000Syntax Error20.6ExplanationUsing unions, we can use same memory location to hold multiple type of data. All member of union uses same memory location which has maximum space. Here ...
Read MoreC Program to check if a number is divisible by any of its digits
Given a number n, task is to find that any of the digit in the number divides the number completely or not. Like we are given a number 128625 is divisible by 5 which is also present in the number.ExampleInput: 53142 Output: yes Explanation: This number is divisible by 1, 2 and 3 which are the digits of the number Input: 223 Output: No Explanation: The number is not divisible by either 2 or 3The approach used below is as follows −We will start from the unit place and take the unit place’s number.Check whether the number is divisible or ...
