Given two fractions with some numerator nume1 and nume2 and deno1 and deno2 as their respective denominator, the task is to compare both the fractions and find out the greater one. Like we have a fraction 1/2 and 2/3 and the higher one is 2/3 because the value of 1/2 is 0.5 and the value of 2/3 is 0.66667 which is higher.Input first.nume = 2, first.deno = 3 second.nume = 4, second.deno = 3Output 4/3Explanation 2/3 = 0.66667 < 4/3 = 1.33333Input first.nume = 1, first.deno = 2 second.nume = 4, second.deno = 3Output 4/3Approach used below is as follows to solve the problem//baadme likhungaAlgorithmStart ...

Given an array arr[] with n number of elements, our task is to check whether the given array is in sorted order or not, If it is in sorted order then print “The array is in sorted order”, else print “The array is not in sorted order”.To solve the above stated problem we can use Iterative or Recursive approach, we will be discussing both.Recursive ApproachSo, what is a Recursive approach? In Recursive approach we recursively call a function again and again until we get the desirable result. In recursive approach the values returned by function is stored in stack memory.Input arr[] ...

Given a string str[], the task is to check whether the string contains any special character and if the string have a special character then print “The String is not accepted” else print “The string is accepted”.Special characters are those characters which are neither numeric nor alphabetic i.e. − !@#$%^&*()+=-\][‘;/., {}|:”?`~So in C Programming language we will use if-else approach to solve the problem.Input − str[] = {“tutorials-point”}Output − the string is not acceptedInput − str[] = {“tutorialspoint”}Output − The string is acceptedApproach used below is as follows to solve the problem −Traverse the whole string.Will look for the special ...

Given a number N with we have to product the number with its largest odd digit. If there is no odd digit then print -1.Like we have initialized N with “153” and the largest odd digit in this number is 5 so the result would be the product of 153 with 5 i.e. 153 * 5 = 765 and if the number has no odd digit like 246 then the output must be -1.Input − N = 198Output − 1782Explanation − 198 * 9 = 1782Input − N = 15382Output − 76910Explanation − 15382 * 5 = 76910Approach used below ...

Given two arrays arr1[] and arr2[] of some size n1 and n2 respectively, we have to find the product of maximum element of first array arr1[] and minimum element of the second array arr2[].Like we have elements in arr1[] = {5, 1, 6, 8, 9} and in arr2[] = {2, 9, 8, 5, 3} so the maximum element in arr1 is 9 and the minimum element in arr2 is 2 so the product of both is 9*2 = 18, likewise we have to write a program to solve the given problem.Input arr1[] = {6, 2, 5, 4, 1} arr2[] = {3, ...

In this problem, we are given two numbers. Our task is to create a C program for the Bitwise recursive addition of two integers.The logic to find the sum using the Bitwise operations is similar to what we used to do when we were in preschool. For finding the sum, we used to add each digit of the number and if a carry is there, we add it to the next digit.We will do a similar thing, find the sum using the XOR operator and check for the carry using the AND operation. If there is a carry we will ... Read More

In this problem, we will learn about the standards that are defined in the C programming language. These are those standard ways in which the program is to be ideally compiled by the compiler as defined by the development community.To understand what I am saying take an easy example of a common C program that you all must have encountered and have seen the issue coming but haven’t got deep into it.The main() function’s void return type −See the following program −void main() {    //program code }This program will run ok if we use the turbo c compiler but ...

In this problem, we are given a student’s record which contains student_id, student_name, student_percentage. Our task is to create a C program to store student records as structure and sort them by name.Let’s take an example to understand the problem, Input − student record ={{ student_id = 1, student_name = nupur, student_percentage = 98}, { student_id = 2, student_name = Akash, student_percentage = 75}, { student_id = 3, student_name = Yash, student_percentage = 62}, { student_id = 4, student_name = Jyoti, student_percentage = 87}, { student_id = 5, student_name = Ramlal, student_percentage = 80}}Output − student record ={{ student_id = ...

Given the task is to find the maximum number of threads that can be created within a process in C.A thread is lightweight process and can be independently managed by the scheduler. Because a thread is a component of a process, therefore multiple number of threads can be associated in a process and also it takes less time for context switching as it is lighter than the process.Threads require less resources than the processes and they also share memory with its peer threads. All user level peer threads are treated as a single task by the operating system. Less time ... Read More

We are given with three binary sequences A, B and C of length N. Each sequence represents a binary number. We have to find no. of flips required of bits in A and B such that XOR of A and B results in C. A XOR B becomes C.First of all let us learn about truth table of XOR operation −XYX XOR Y000011101110From the above table we observe that for the same values in X and Y, X XOR Y results 0 else it results 1. So this will be helpful for finding bits to be flipped in A and ... Read More
