C program to compare the structure variables
In C programming language, a structure is a collection of different datatype variables, which are grouped together under a single name. While C doesn't provide a built-in operator to compare entire structures directly, we can compare structure variables by comparing their individual members. Syntax struct tagname { datatype member1; datatype member2; datatype membern; }; Structure Declaration and Initialization The general form of a structure declaration is as follows − struct tagname { datatype member1; ...
Read MoreExplain queue by using linked list in C language
A queue is a linear data structure that follows the First In First Out (FIFO) principle. When implemented using linked lists, we can avoid queue overflow and underflow issues that occur with array-based implementations. The linked list provides dynamic memory allocation, allowing the queue to grow or shrink as needed. Operations carried out on a queue using linked lists in C programming language are as follows − Enqueue − Insert an element at the rear Dequeue − Remove an element from the front Display − Show all elements in the queue Front − Get the front element ...
Read MoreExplain the stack by using linked list in C language
A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. When implementing a stack using a linked list in C, we can avoid stack overflow and underflow issues by dynamically allocating memory. This approach provides flexibility in memory usage and can grow or shrink based on requirements. Syntax struct node { int data; struct node *next; } *top; void push(int value); void pop(); int peek(); int isEmpty(); Stack Operations The primary operations performed on a stack using linked list are − ...
Read MoreExplain the deletion of element in linked list
Linked lists use dynamic memory allocation which allows them to grow and shrink during runtime. A linked list is a collection of nodes where each node contains two parts: data (stores the value) and link (points to the next node). Data Link Data Link Data Link NULL ...
Read MoreC program to calculate the standard deviation
Standard deviation is used to measure deviation of data from its mean. The mathematical formula to calculate the standard deviation is as follows − $$s=\sqrt{Variance}$$ where Variance$$=\frac{1}{n}\:\:\displaystyle\sum\limits_{i=1}^n (x_{i}-m)^{2}$$ and $$m=mean=\frac{1}{n}\:\displaystyle\sum\limits_{i=1}^n x_{i}$$ Syntax #include double sqrt(double x); Algorithm Refer an algorithm given below to calculate the standard deviation for the given numbers − Step 1 − Read n items. Step 2 − Calculate sum and mean of the items. Step 3 − Calculate variance. Step 4 − Calculate standard deviation. The logic used in the ...
Read MoreC Program to represent a multiplication table.
In C programming, a multiplication table displays the products of numbers in a systematic grid format. This program creates a 12x10 multiplication table where each row represents multiples of a number from 1 to 12. Syntax for(int i = 1; i
Read MoreC program to calculate range of values and an average cost of a personal system.
A personal system is sold at different costs by vendors. To analyze the pricing data, we need to calculate statistical measures like the average cost and range of values. Let's take the list of costs (in hundreds) quoted by some vendors − 25.00, 30.50, 15.00, 28.25, 58.15, 37.00, 16.65, 42.00, 68.45, 53.50 Syntax Range = Highest Value - Lowest Value Average = Sum of All Values / Total Count Solution The range is the difference between the highest and lowest values in a dataset. The average is the sum of all values divided ...
Read MoreC Program to calculate the salesmen salary with macro functions.
In C programming, macro functions provide a way to define constants and simple calculations that are processed during compilation. This program demonstrates how to calculate a salesman's salary using predefined macro constants for base salary, bonus rates, and commission percentages. Problem Statement A laptop manufacturing company has the following monthly compensation policy for their salespersons − Minimum base salary: 3000.00 Bonus for every laptop sold: 200.00 Commission on total monthly sales: 5 percent Since laptop prices change monthly, the sales price of each laptop is fixed at the beginning of every month. Syntax ...
Read MoreC program to find out cosine and sine values using math.h library.
In C programming, the math.h library provides trigonometric functions like cos() and sin() to calculate cosine and sine values. These functions take angles in radians as input and return the corresponding trigonometric values. Syntax #include double cos(double x); // Returns cosine of x (in radians) double sin(double x); // Returns sine of x (in radians) Parameters x − The angle in radians for which to calculate the trigonometric value Return Value Both functions return a double value representing the cosine or sine of the ...
Read MoreHow to multiply two matrices using pointers in C?
Matrix multiplication is a fundamental operation in linear algebra. In C programming, we can multiply two matrices using pointers to access matrix elements efficiently. This approach demonstrates how pointer arithmetic works with 2D arrays. Syntax // Matrix multiplication using pointers *(*(result + i) + j) = sum of (*(*(mat1 + i) + k)) * (*(*(mat2 + k) + j)) Understanding Pointer Access in 2D Arrays When working with 2D arrays and pointers − mat[i][j] is equivalent to *(*(mat + i) + j) mat + i points to the i-th row *(mat + ...
