The  nPr termed as permutation. They are useful in finding possible permutation of the number in the sets of numbers. To calculate combinations, we will use the formula nPr = n! /  (n – r)! , where n represents the total number of items, and r represents the number of items being chosen at a time. […]

The nCr also termed as a combination. Combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)! , where n represents the total number of items, and

Before writing the C program to check whether a triangle is valid or not if angles are given, we should know the properties of triangles. The angle property of the triangle says that the sum of all three angles should be equal to 180. #include <stdio.h> int main() { //variable to store angles int angle1,

Before writing the C program to check whether the triangle is isosceles, we should know the properties of equilateral triangles. In geometry, an isosceles triangle is a triangle that has two sides of equal length. #include <stdio.h> int main() { int side1, side2, side3; //Get sides of a triangle from the user printf(“Enter sides of

Before writing the C program to check whether the triangle is equilateral, we should know the properties of equilateral triangles. In geometry, an equilateral triangle is a triangle in which all three sides are equal. #include <stdio.h> int main() { int side1, side2, side3; //Get sides of a triangle from the user printf(“Enter sides of

C program to find largest of three given numbers is discussed here. Input three integers from the user and find the largest number among them. Given three numbers num1,num2, and num3. The task is to find the largest number among the three. Example, Input: num1= 2, num2 = 18, num3= 10 Output: Largest number =

  #include<stdio.h> int main() { int num, rem, sum = 0; // Ask user to enter the number printf(“Enter a number: “); // Read two number from the user scanf(“%d”, &num); while(num != 0) { rem = num % 10; sum += rem; num = num / 10; } printf(“sum = %d”, sum); return 0;

How to write a sample C program to print Hello World? It is the first program to start any programming language. The “Hello World” program helps to understand the basic programming structure of C Programming. So let see how we can write print Hello World using C language.   #include <stdio.h> int main() { printf(“Hello
