C Program for product of array
Given an array arr[n] of n number of elements, the task is to find the product of all the elements of that array.Like we have an array arr[7] of 7 elements so its product will be likeExampleInput: arr[] = { 10, 20, 3, 4, 8 } Output: 19200 Explanation: 10 x 20 x 3 x 4 x 8 = 19200 Input: arr[] = { 1, 2, 3, 4, 3, 2, 1 } Output: 144The approach used below is as follows −Take array input.Find its size.Iterate the array and Multiply each element of that arrayShow resultAlgorithmStart In function int prod_mat(int arr[], ...

Given a number n and we have to print the arrow star pattern of maximum n number of stars.The star pattern of input 4 will look like −ExampleInput: 3 Output:Input: 5 Output:The approach used below is as follows −Take input in integer.Then print n spaces and n stars.Decrement till n>1.Now increment till n.And print spaces and stars in increasing order.AlgorithmStart In function int arrow(int num) Step 1-> declare and initialize i, j Step 2-> Loop For i = 1 and i
Read MoreC Program to check if a number is divisible by sum of its digits
Given a number n we have to check whether the sum of its digits divide the number n or not. To find out we have to sum all the numbers starting from the unit place and then divide the number with the final sum.Like we have a number “521” so we have to find the sum of its digit that will be “5 + 2 + 1 = 8” but 521 is not divisible by 8 without leaving any remainder.Let’s take another example “60” where “6+0 = 6” which can divide 60 and will not leave any remainder.ExampleInput: 55 Output: ...
Read MoreC Program to check if the points are parallel to X axis or Y axis
Given n number of points we have to check that whether the point is parallel to x-axis or y-axis or no axis according to a graph. A graph is a figure which is used to show a relationship between two variables each measured along with axis at right angles. Parallel are the same lines which are having same distance at all points, like railway tracks are parallel to each other.So, we have to find whether the points are parallel to x-axis or y-axis means the distance between the coordinates and the axis are same at all points.What is an axisThe ...
Read MoreC Program for replacing one digit with other
Given a number n, we have to replace a digit x from that number with another given number m. we have to look for the number whether the number is present in the given number or not, if it is present in the given number then replace that particular number x with another number m.Like we are given with a number “123” and m as 5 and the number to be replaced i.e. x as “2”, so the result should be “153”.ExampleInput: n = 983, digit = 9, replace = 6 Output: 683 Explanation: digit 9 is the first digit ...
Read MoreC Program for Reversed String Pattern
Given a string str, our task is to print its reversed pattern. The Pattern will be incremental in reversed order, and when the string is completed fill ‘*’ in the remaining places.Like we enter a string “abcd”, now in first line we have to print “a” then in next line we have to print “cb” and then in third line we will print “**d”.ExampleInput: str[] = { “abcd” } Output: a c b * * dExplanation −In first line print 1 characterIn second line print 2 characters in reverse orderIn third line Print 3 characters in reverse order, if the ...
Read MoreC Program to check if an Array is Palindrome or not
Given an array arr[] of any size n, our task is to find out that the array is palindrome or not. Palindrome is a sequence which can be read backwards and forward as same, like: MADAM, NAMAN, etc.So to check an array is palindrome or not so we can traverse an array from back and forward like −ExampleInput: arr[] = {1, 0, 0, 1} Output: Array is palindrome Input: arr[] = {1, 2, 3, 4, 5} Output: Array is not palindromeApproach used below is as follows −We will traverse the array from starting as well as from the end until ...
Read MoreC Program to check Plus Perfect Number
Given a number x with n number of digits, our task is to check whether the given number’s Plus Perfect number or not. In order to check that the number is Plus Perfect Number we find the nth power of every digit d (d^n) and then sum all the digits, if the sum is equal to n then the number is Plus Perfect Number. Plus Perfect number is similar like finding an Armstrong of any number.Like In the given example below −ExampleInput: 163 Output: Number is not a perfect_number Explanation: 1^3 + 6^3 + 3^3 is not equal to 163 ...
Read MoreC Program to convert first character uppercase in a sentence
Given a string and with mixed case, i.e with both uppercase and lower case, the task is to covert the first character to uppercase rest in lowercase if it’s in upper case.Let’s understand it in depth with the help of a simple example.Like we are given a string “hElLo world”, we have to convert the first character ‘h’ which is in lowercase to uppercase ‘H’ and rest all letters before the space or end of the string to lowercase.Moreover when we encounter first character after a space we have to convert it to uppercase.ExampleInput: str[] = {“heLlO wORLD”} Output: Hello ...
Read MoreC Program to check if a date is valid or not
Given date in format date, month and year in integer. The task is to find whether the date is possible on not.Valid date should range from 1/1/1800 – 31/12/9999 the dates beyond these are invalid.These dates would not only contains range of year but also all the constraints related to a calendar date.Constraints are −Date can’t be less than 1 and more than 31Month can’t be less than 1 and more than 12Year can’t be less than 1800 and more than 9999When the months are April, June, September, November the date can’t be more than 30.When the month is February ...
