C program to find the area of circle and cylinder using structures.
In C programming, we can calculate the area of a circle and the surface area and volume of a cylinder using structures to organize related data. A structure helps group related geometric properties like radius, height, and calculated areas in a single unit. Syntax struct shape { float radius; float height; float areacircle; float areacylinder; float volumecylinder; }; Formulas Used Area of circle: π × radius² Surface area of cylinder: 2π × radius ...
Read MoreWhat is an anagram in C language?
An anagram is a word or phrase formed by rearranging the letters of another word or phrase, using all original letters exactly once. In C programming, we check if two strings are anagrams by comparing the frequency of each character in both strings. Two strings are anagrams if they contain the same characters with the same frequency, regardless of their order. For example, "listen" and "silent" are anagrams because both contain one 'l', one 'i', one 's', one 't', one 'e', and one 'n'. Syntax int check_anagram(char str1[], char str2[]); Algorithm The anagram ...
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. Syntax nCr = n! / (r! * (n-r)!) nPr = n! / (n-r)! Permutations and Combinations Formulas The formulas to find the permutation and combination of given numbers in C language are given below − ...
Read MoreC program to perform intersection operation on two arrays
In C programming, an array intersection operation finds all common elements between two arrays. The intersection of two arrays contains only the elements that appear in both arrays, without duplicates. Syntax for(i=0; i
Read MoreC program to perform union operation on two arrays
The union operation on arrays combines all elements from both arrays while eliminating duplicates. This is similar to the mathematical set union operation, where each element appears only once in the result. Syntax int unionArrays(int arr1[], int size1, int arr2[], int size2, int result[]); Union Operation Example Given two arrays: Array 1 = {1, 2, 3, 4, 6} Array 2 = {1, 2, 5, 6, 7} The union operation produces: Array1 ∪ Array2 = {1, 2, 3, 4, 5, 6, 7} Array 1 ...
Read MoreWhat is a simple assertion in C language?
An assertion is a statement used to declare positively that a fact must be true when that line of code is reached. Assertions are debugging tools that help catch programming errors during development by validating expected conditions. Syntax assert(expression); Where expression is a condition that should evaluate to true. The assert() macro is defined in the assert.h header file. How Assertions Work True condition: When the expression is true, the program continues normally with no action. False condition: When the expression is false, the program terminates and displays an error message with ...
Read MoreC Program to find sum of perfect square elements in an array using pointers.
In C programming, finding the sum of perfect square elements in an array using pointers involves traversing the array with pointer arithmetic and checking if each element is a perfect square. A perfect square is a number that can be expressed as the product of an integer with itself (e.g., 1, 4, 9, 16, 25). Syntax int isPerfectSquare(int num); int sumPerfectSquares(int *arr, int size); Algorithm Step 1 − Read the number of elements in the array. Step 2 − Input the array elements. Step 3 − Initialize sum = 0 and declare a pointer ...
Read MoreC program to represent the numbers in spiral pattern
In C programming, a spiral pattern displays numbers in alternating left-to-right and right-to-left order across rows. This creates a visual spiral effect where consecutive pairs of numbers appear in different orders on each row. Spiral Pattern 1 2 4 3 5 6 8 7 Blue: Left to Right Red: Right to Left Pattern alternates every row Syntax for(i=1; i
Read MoreC program to find type of array entered by the user.
In C programming, we can classify an array based on the type of numbers it contains. An array can be classified as an even array (all elements are even), an odd array (all elements are odd), or a mixed array (contains both even and odd elements). Algorithm Here's the approach to determine the array type − Read the array size and elements from user Count even and odd numbers in separate counters Compare counters with total size to determine array type Display the result based on the comparison Example The following program demonstrates ...
Read MoreC Program to display the numbers in X pattern
In C programming, displaying numbers in an X pattern is a common pattern printing exercise. The X pattern consists of numbers arranged such that they appear on the main diagonal (top-left to bottom-right) and anti-diagonal (top-right to bottom-left) of a square grid. Syntax for(i = 0; i < rows; i++) { for(j = 0; j < rows; j++) { if(i == j || i + j == rows - 1) { printf("%d", i ...
