In this article we will learn to implement a C program to print all values in an array less than given number. A C program is provided below to print all the values in an array which are less than the given key element. The program is as follows: #include <stdio.h> #include <conio.h> int […]
In this article we will try to implement a C program to print a pattern of numbers as a pyramid. A C program is provided below to print the following pattern: 1 2*2 3*3*3 4*4*4*4 4*4*4*4 3*3*3 2*2 1 Take starting value as 1 and n = 4. The program is as follows: […]
In this article we will learn to implement a C program to check balanced parentheses. A C program is provided below to match parentheses in a giving string. The logic used is to maintain counts for each occurrence of ‘(‘ and ‘)’. If the difference between these counts is zero, then we can say […]
In this article we will try to implement a C program to multiply consecutive numbers in an array. A C program is provided below to find the product of consecutive numbers in a given array. For example if the given array is: 1 2 5 4 1 2, then the output should be 1*2*1*2, […]
In this article we will learn to implement a C program to find number of duplicate elements in an array. A C program is provided below which reads a list of number and prints the number of duplicates in a given array. Note: This program only works if the numbers are repeated for 2 […]
In this article we will learn to implement a C program to print prime numbers up to n. A C program is provided below which accepts n as input from user and prints all the prime numbers up to n. The program is as follows: #include <stdio.h> #include <conio.h> #include <math.h> int main() { […]
In this article we will learn to implement a C program to print a pattern. A C program is provided below to print the following pattern when n is given as 3 1 2*3 4*5*6 2*3 1 Program to print the pattern is given below: #include <stdio.h> #include <conio.h> int main() { int n; […]
In this article we will learn to implement a C program to print a pattern of numbers. A C program is given below for printing a numbers pattern. Given starting number of a pattern and value of n, print the pattern as given below If starting value = 3 and n = 4 then […]
In this article we will learn to implement a C program to swap the contents and indexes in an array. A C program is provided below for swapping the array element with the corresponding array index number. Given an array with size n and its contents are from 0 to n-1. Swap the index […]
