Maximum difference of sum of elements in two rows in a matrix in C
We are given a matrix and the task is to find the greatest difference between the sum of elements in two rows of a matrix. Suppose we have a matrix M[i,j] with i rows and j columns. Let the rows be R0 to Ri-1. The difference will be calculated by subtracting the (sum of elements of Ry) - (sum of elements of Rx), where x
Read MoreProgram for sum of geometric series in C
In C programming, calculating the sum of a geometric series involves finding the total of terms where each term is obtained by multiplying the previous term by a constant ratio. A geometric series follows the pattern: a, ar, ar2, ar3, ..., where 'a' is the first term, 'r' is the common ratio, and 'n' is the number of terms. Syntax float sumGeometric(float a, float r, int n); Parameters a − First term of the geometric series r − Common ratio between successive terms n − Number of terms in the series ...
Read MoreProgram for triangular patterns of alphabets in C
In C programming, triangular patterns of alphabets are commonly used to demonstrate nested loops and character manipulation. This pattern starts with a full line of consecutive alphabets and removes one character from the beginning in each subsequent line. Syntax for (i = 1; i
Read MoreProfit and loss Problems using C
In C programming, profit and loss problems involve calculating the financial gain or loss from a transaction based on the cost price and selling price. Given a cost price (cp) and selling price (sp), we need to determine whether a profit was earned, a loss was suffered, or there was no profit nor loss. Syntax // Basic profit and loss calculation if (selling_price > cost_price) { profit = selling_price - cost_price; } else if (cost_price > selling_price) { loss = cost_price - selling_price; } else { ...
Read MoreProduct of given N fractions in reduced form in C
Given the numerator and denominator of N fractions, the task is to find the product of all N fractions and output the result in reduced form. The product of fractions is calculated by multiplying all numerators together and all denominators together, then reducing the resulting fraction to its simplest form. For example, if we have fractions 4/5 and 3/4, their product would be (4×3)/(5×4) = 12/20, which reduces to 3/5. Fraction Multiplication: 4/5 × 3/4 = (4×3)/(5×4) = 12/20 = 3/5 4 5 ...
Read MoreProgram to Add Two Complex Numbers in C
Given are two complex numbers in the form of a1 + ib1 and a2 + ib2, the task is to add these two complex numbers in C programming. Complex numbers are those numbers which can be expressed in the form of "a + ib" where "a" and "b" are real numbers and "i" is the imaginary unit which satisfies i² = −1. Since no real number satisfies this equation, it is called the imaginary unit. Syntax struct complex { int real; int imaginary; }; struct complex addComplex(struct ...
Read MoreProduct of middle row and column in an odd square matrix in C
Given a square matrix, mat[row][column] where row and column are equal and are of odd length, the task is to find the product of middle row and middle column of that matrix. The matrix must have odd dimensions so there's always a clear middle row and column. 1 2 3 4 5 ...
Read MoreProgram to compare two fractions in C
In C programming, comparing two fractions requires cross-multiplication to avoid floating-point precision issues. Given two fractions with numerators and denominators, we need to determine which fraction has the greater value. Syntax struct Fraction { int nume, deno; }; struct Fraction greater(struct Fraction first, struct Fraction second); Approach To compare fractions a/b and c/d, we use cross-multiplication: if a*d > b*c, then a/b > c/d. This avoids floating-point division and maintains precision. Example 1: Basic Fraction Comparison This example compares 4/5 and 3/4 using cross-multiplication − ...
Read MoreProgram to check if an array is sorted or not (Iterative and Recursive) in C
Given an array arr[] with n number of elements, our task is to check whether the given array is in sorted order or not. If it is in sorted order then print "The array is in sorted order", else print "The array is not in sorted order". To solve this problem we can use iterative or recursive approach, we will be discussing both. Syntax int isSorted(int arr[], int n); Method 1: Iterative Approach In iterative approach, we use loops to traverse the array and compare adjacent elements ? #include ...
Read MoreProgram to check if a string contains any special character in C
In C programming, checking if a string contains special characters is a common validation task. Special characters are those that are neither alphabetic nor numeric, such as symbols like !@#$%^&*() etc. Syntax int checkSpecialCharacter(char str[], int length); Method 1: Using Character Comparison This method iterates through each character and compares it against a predefined set of special characters − #include #include int checkSpecialCharacter(char str[], int n) { int i; for (i = 0; i < n; i++) { ...
