C 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 + ...
Read MoreWrite a C program to print all files and folders.
In C programming, we can list all files and folders in a directory using directory handling functions. This requires the dirent.h header which provides structures and functions to work with directory entries. Syntax DIR *opendir(const char *dirname); struct dirent *readdir(DIR *dirp); int closedir(DIR *dirp); Key Functions opendir() − Opens a directory stream for reading readdir() − Reads directory entries one by one closedir() − Closes the directory stream Note: This program uses dirent.h which is POSIX standard. On Windows with certain compilers, you might need additional setup or use platform-specific ...
Read MoreExplain the quick sort technique in C language.
Quick sort is a highly efficient divide-and-conquer sorting algorithm that works by selecting a 'pivot' element and partitioning the array around it. Elements smaller than the pivot go to the left, and larger elements go to the right, then the process is repeated recursively on both subarrays. How Quick Sort Works The quick sort algorithm follows these steps − Step 1: Choose a pivot element from the array (typically the first, last, or middle element) Step 2: Partition the array so elements less than pivot are on the ...
Read MoreC program to print the ASCII values in a string.
In C programming, we can print the ASCII values of characters in a string by iterating through each character and using the %d format specifier to display its numeric ASCII value. Syntax while(str[i] != '\0') { printf("ASCII Value of %c = %d", str[i], str[i]); i++; } String Declaration and Initialization A string in C is an array of characters terminated by a null character '\0'. Declaration: char stringname[size]; Initialization methods: Using character constants: char string[10] = ...
Read MoreC Program to print all ASCII values.
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values to characters. In C programming, we can print ASCII values of characters using format specifiers without explicitly converting characters to integers. Syntax printf("%c \t %d", i, i); Method 1: Printing ASCII Values from A to z (65 to 122) This example prints ASCII values for uppercase letters, special characters, and lowercase letters − #include int main() { int i; printf("Character \t ASCII Value"); // Print ASCII values from A to z for (i = 65; i = 32 && i
Read MoreC program to remove spaces in a sentence using string concepts.
In C, removing spaces from a string involves iterating through the string and eliminating space characters. This can be accomplished using string manipulation techniques where we shift characters to overwrite spaces. Syntax while(string[i] != '\0') { if(string[i] == ' ') { // Shift characters left to remove space } i++; } String Declaration and Initialization An array of characters is called a string. Given below is the declaration of a string − ...
