Differentiate between int main and int main(void) function in C
In C programming, there is a subtle but important difference between int main() and int main(void). Both declare the main function to return an integer, but they differ in how they handle function parameters. Syntax int main() { // Function body return 0; } int main(void) { // Function body return 0; } The int main() Function The int main() function with empty parentheses indicates that the function can accept any number of arguments. In C, when ...
Read MoreWhat are string searching functions in C language?
String searching functions in C are built-in library functions that help locate specific characters, substrings, or patterns within strings. These functions are part of the standard C library (string.h) and provide efficient ways to search and analyze string content. Syntax #include char *strchr(const char *str, int c); char *strrchr(const char *str, int c); char *strpbrk(const char *s1, const char *s2); size_t strspn(const char *s1, const char *s2); size_t strcspn(const char *s1, const char *s2); char *strtok(char *s1, const char *s2); char *strtok_r(char *s1, const char *s2, char **saveptr); String Searching Functions Overview ...
Read MoreWhat are memory operations in C language?
Memory operations in C are functions that manipulate raw bytes in memory, regardless of data type. These functions are declared in #include and work with void* pointers to handle any data type. Syntax The five primary memory functions have the following prototypes − void *memchr(const void *s, int c, size_t n); int memcmp(const void *s1, const void *s2, size_t n); void *memcpy(void *dest, const void *src, size_t n); void *memmove(void *dest, const void *src, size_t n); void *memset(void *s, int c, size_t n); Memory Functions Overview ...
Read MoreC program to store inventory system using structures
In C programming, an inventory management system can be efficiently implemented using structures to store and organize product information. Structures allow us to group related data of different types under a single entity, making it perfect for managing inventory details like item names, codes, quantities, prices, and manufacturing dates. Syntax struct structure_name { datatype member1; datatype member2; /* more members */ }; Features of Structures The key features of structures in C programming are − Enables grouping of different data ...
Read MoreC program to sort names in alphabetical order using structures
Structure is a collection of different datatype variables, grouped together under a single name. In this article, we will learn how to sort names in alphabetical order using structures in C. Syntax struct structure_name { datatype member1; datatype member2; // ... more members }; Features of Structure The features of structure in the C programming language are as follows − It is possible to copy the contents of all the structure elements of different datatypes to another structure variable of ...
Read MoreC program to compare if the two matrices are equal or not
In C programming, comparing two matrices for equality involves checking both their dimensions and corresponding elements. Two matrices are considered equal if they have the same dimensions (rows and columns) and all corresponding elements are identical. Syntax // Matrix comparison logic if (rows1 == rows2 && cols1 == cols2) { // Compare each element for (int i = 0; i < rows1; i++) { for (int j = 0; j < cols1; j++) { ...
Read MoreC program to sort all columns and rows of matrix
In C programming, sorting matrix rows and columns involves rearranging elements within each row in ascending order and elements within each column in descending order. This operation requires nested loops to traverse and compare matrix elements. Syntax /* Row sorting (ascending) */ for (i = 0; i < rows; i++) { for (j = 0; j < cols; j++) { for (k = j + 1; k < cols; k++) { if (matrix[i][j] ...
Read MoreC program to interchange the diagonal elements in given matrix
In C programming, interchanging the diagonal elements of a matrix involves swapping the main diagonal elements with the secondary (anti) diagonal elements. This operation is only possible with square matrices where the number of rows equals the number of columns. Syntax /* Logic to interchange diagonal elements */ for (i = 0; i < n; i++) { temp = matrix[i][i]; /* Store main diagonal element */ matrix[i][i] = matrix[i][n-i-1]; /* Assign ...
Read MoreC program to perform operations on two halves' in a single array
In C programming, we can perform different operations on two halves of a single array. This approach is useful when you need to apply distinct sorting criteria to different portions of your data. Let's explore how to split an array into two halves and sort the first half in ascending order while sorting the second half in descending order. Syntax // Splitting array into two halves int mid = n / 2; // where n is array size // Bubble sort for ascending order (first half) for (i = 0; i < mid; i++) { ...
Read MoreC program to generate the value of x power n using recursive function
In C programming, calculating xn (x raised to the power n) can be efficiently done using recursive functions. This approach breaks down the problem into smaller subproblems, making the solution elegant and mathematically intuitive. Syntax long int power(int x, int n); Algorithm The recursive algorithm uses the following mathematical properties − If n = 1, then xn = x (base case) If n is even, then xn = (xn/2)2 If n is odd, then xn = x × xn-1 Example: Recursive Power Function Here's a complete C program that ...
