Given an integer array arr[] a non negative integer k, print k-th distinct element in an array. The given array may contain duplicates and the output should print k-th distinct element among all elements in the array. If k is more than number of distinct elements, print -1. Examples : Input : arr[] = {1, 2, 1, 3,… Read More »
Design the pattern as represented in the famous snake and ladders game. Your task is to print the pattern as represented in snake and ladders game for a given integer input N, where N denotes the number of rows and columns of the pattern array. Note: N given will be always even. Examples: Input: N=4 Output: 7 8… Read More »
In this article, we will discuss the various opportunities available to a person who is well-equipped with the necessary skills in C / C ++ language. C and C ++ programming languages are old, but still popular among computer science people. Even a person with a non-technical background has heard of these languages. C is popular due to… Read More »
In this article, we have discussed various methods to add two numbers in C++. These are simple program, you can learn them easily. Method-1 : With Hardcoded Inputs Output: 11 Method-2 : With user Inputs Output: Output depends on user inputs, that will be sum of both numbers. Method-3 : With class Output: Output depends on user inputs,… Read More »
Array is collection of items having same data type stored in contiguous memory location. An array is derived data type in C programming language which can store similar types of data in contiguous memory locations. Data may be primitive type, (i.e., int, char, float, double), address of union, structure, pointer, function or another array. Array implementation is important… Read More »
1. C language : C was developed by Dennis Ritchie between the year 1969 and 1973 at AT&T Bell Labs to write Operating System. It is a procedural programming language and does not support classes and objects. 2. C++ language : C++ was developed by Bjarne Stroustrup in 1979. It has imperative, object-oriented and generic programming features. C++… Read More »
These two can be allowed by some compiler, but does not a standard. In both language C and C++, there is standard for it. In case ‘main()’ or ‘void main()’ : We can ignore return type only if a systems that does not provide such a facility. But, if system provide return type facility then there can be… Read More »
1. Inline : It is normal function that is inline keyword and expanded by the compiler. Its arguments are evaluated only once. Syntax of an Inline function: 2. Macro : It is also called preprocessors directive and these are defined by the #define keyword. Syntax of Macro: Macros are just "copy paste" in the code before the compilation.… Read More »

Actually, “- – >” is not an operator, but this is combination of two separate operators, “- -” and “>” . So, if you write it as It will print following output, 9 8 7 6 5 4 3 2 1 0 Because conditional’s code decrements x, while (x- – > 0) Statement could be written as follows:… Read More »
