What is an anagram in C language?
Anagram strings are nothing but, all the characters that occur for the same number of times in another string, which we call as anagrams.A user enters two strings. We need to count how many times each letter ('a' to 'z') appears in them and then, compare their corresponding counts. The frequency of an alphabet in a string is how many times it appears in it.If two strings have same count of the frequency of particular alphabet then, we can say those two strings are anagrams.Example 1String 1 − abcdString 2 − bdacThese two strings have same letters which appear once. ...
Read MoreC Program find nCr and nPr.
In C programming language, nCr is referred as the combination. nCr is the selection of r objects from a set of n objects, where the order of objects does not matter.nPr is referred as the permutation. nPr is arrangement of 'r' objects from a set of 'n' objects, which should be in an order or sequence.Permutations and combinations formulasThe formulas to find the permutation and combination of given numbers in C language are given below −nCr = n!/(r!*(n-r)!)nPr = n!/(n-r)!.The logic used to find nCr is as follows −result = factorial(n)/(factorial(r)*factorial(n-r));The logic used to find nPr is as follows −result ...
Read MoreC Program to find sum of perfect square elements in an array using pointers.
ProblemWrite a program to find the sum of perfect square elements in an array by using pointers.Given a number of elements in array as input and the sum of all the perfect square of those elements present in the array is output.SolutionFor example, Input= 1, 2, 3, 4, 5, 9, 10, 11, 16 The perfect squares are 1, 4, 9, 16. Sum = 1 + 4 + 9 +16 = 30 Output: 30AlgorithmRefer an algorithm given below to find the sum of perfect square elements in an array by using pointers. Step 1 − Read number of elements in array at ...

Refer an algorithm given below for the C program to display the numbers in X pattern.AlgorithmStep 1: Start Step 2: Declare variables Step 3: Read number of rows Step 4: for loop satisfiesif(i==j || i+j==rows-1)print i+1Print " "Step 5: Print new line Step 6: StopThe logic to print numbers in X pattern is as follows −for(i=0;i
Read MoreC program to remove the brackets from a given input.
ProblemLet’s create a simplified expression by removing brackets from the expressions.SolutionExample 1Input: A string expression with bracket is as follows: (x+y)+(z+q) The output is as follows: x+y+z+qExample 2The input is as follows: (x-y+z)-p+q The output is as follows: x-y+z-p+qAlgorithmRefer an algorithm to remove the brackets from a given input.Step 1: Declare and read the input at runtime.Step 2: Traverse the string.Step 3: Copy each element of the input string into new string.Step 4: If anyone parenthesis is encountered as an element, replace it with empty space.ExampleFollowing is the C program to remove the brackets from a given input −#include int ...
Read MoreExplain queue by using linked list in C language
Queue overflow and Queue under flow can be avoided by using linked list.Operations carried out under queue with the help of linked lists in C programming language are as follows −InsertDeleteInsertionThe syntax is as follows −Syntax&item : Newnode = (node*) mallac (sizeof (node)); newnode ->data = item; newnode ->link = NULL; if ((front = = NULL) || (rear = = NULL)){ front= newnode; rear = newnode; }else{ Rear->link = newnode; rear = newnode; }DeletionThe syntax is as follows −Syntaxif ((front= = NULL)) printf("Deletion is not possible, Queue is empty"); else{ temp = front; front ...
Read MoreExplain the stack by using linked list in C language
Stack over flow and stack under flow can be avoided by allocating memory dynamically.Operations carried out under stack in C programming language are as follows −PushPopPushFollowing is the basic implementation of a linked list −&item = 10 newnode = (node*) malloc (sizeof (node)); newnode ->data = item; newnode ->link = NULL; newnode ->link = start; start = newnode;popThe syntax is as follows −Syntaxif (start = = NULL) printf("Deletion is not possible.List is empty") else{ temp = start; start = start link; free (temp); }ProgramFollowing is the C program for stack by using linked lists −#include #include ...
Read MoreHow communication among functions is established in C language?
Functions communicate among themselves with the help of arguments and return value.Farm of ‘C’ function is as follows −return-datatype function name (argument list){ local variable declarations; executable statements(s); return (expression); }For example, void mul (int x, int y){ int p; p=x*y; printf("product = %d”, p); }Return values and their typesA function may or may not send back a value to the calling function.It will be done by using the return statementThe return types are void, int, float, char and double.If a function is not returning any value, then its return type is ‘void’.Function nameA ...
