Pascal's triangle is the representation of integers in the form of a triangle. One of the famous representations of it is with binomial equations. We can use combinations and factorials to achieve this.Constructing a Pascal triangleAll values outside the triangle are considered zero (0). The first row is 0 1 0 whereas only 1 acquire a space in Pascal’s triangle, 0s are invisible. The second row is acquired by adding (0+1) and (1+0). The output is sandwiched between two zeroes. The process continues till the required level is achieved.Programmatically, a Pascal triangle is defined as an array constructed by adding ... Read More

Floyd's triangle is a right-angle triangle of consecutive numbers, starting with a 1 in the top left corner −For example,1 2 3 4 5 6 7 8 9 10Example 1 Live Demo#include int main(){    int rows, i,j, start = 1;    printf("Enter no of rows of Floyd's triangle :");    scanf("%d", &rows);    for (i = 1; i

ProblemHow to check whether the given number is an Armstrong number or not using C Programming language?SolutionArmstrong number is the number that is equal to the sum of cubes of its digits.Syntaxpqrs………=pow(p, n)+pow(q, n)+pow(r, n)+……….For example, 153, 371, 1634, etc., are Armstrong numbers.153=1*1*1 + 5*5*5 + 3*3*3    =1+125+27    =153 (Armstrong number)Program Live Demo#include int main(){    int number, remainder, total=0, temp;    printf("enter the number=");    scanf("%d", &number);    temp=number;    while(number>0){       remainder=number%10;       total=total+(remainder*remainder*remainder);       number=number/10;    }    if(temp==total)       printf("This number is Armstrong number");    else   ...

ProblemHow to print the given two-digit number in reverse order with the help of division and Modulo operator using C programming language?SolutionSo far, we had seen how to reverse the string using string function and without string function. Now let’s see how to reverse the two-digit number without using the predefined function.The logic we use to reverse the number with the help of operators is −int firstno=number%10; //stores remainder int secondno=number/10;// stores quotientThen print the first number followed by the second number then you will get the reverse number for the given number.Program 1In this example, we will take a ...

Modulo − Represents as % operator. And gives the value of the remainder of an integer division.Division − represents as / operator. And gives the value of the quotient of a division.Program 1#include int main(){    int a, b, c;    printf("enter a, b, c values:");    scanf("%d%d%d, &a, &b, &c);    printf("a/b=%d a%b=%d", a/b, a%b);    printf("(a+10)%b=%d (a+10)/b=%d", (a+10)%b, (a+10)/b); }Outputenter a, b, c values:2 4 6 a/b=0 ab=2 (a+10)b=0 (a+10)/b=3Program 2Applying pointer variables to perform modulo and division operation − Live Demo#include void main(){    //Declaring pointers and variables//    int num1, num2;    int *p1, *p2;    p1=&num1;    p2=&num2; ...

ProblemHow to cast vote, count, and display the votes for each candidate that participates in elections using C language?SolutionLet’s consider three persons who participated in elections. Here we need to write a code for the following −Cast vote − Selecting a candidate by pressing the cast voteFind vote count − Finding the total number of votes each candidate gains declaring the winner.ExampleAll these operations are performed by calling each function using Switch case −#include #define CANDIDATE_COUNT #define CANDIDATE1 "ABC" #define CANDIDATE2 "XYZ" #define CANDIDATE3 "PQR" int votescount1=0, votescount2=0, votescount3=0; void castvote(){    int choice;    printf(" ### Please choose your ...

By using justifications in the printf statement, we can format the data in various ways. To implement the right justification, insert a minus sign before the width value in the %s character. printf("%-15s", text); Program 1 The example below prints a table with name and amounts, formatted in two columns with fixed widths for better alignment, using printf() for row and column-wise output. #include int main(){ char a[20] = "Names", b[20]="amount to be paid"; char a1[20] = "Bhanu", b1[20]="Hari", c1[20]="Lucky", d1[20]="Puppy"; int a2 = 200, b2 = 400, c2 = ...
