Binary Search

A binarysearch program locates the position of an item in a sorted array. Logic: The Binary search starts by testing the element at the middle of the array. Let us consider an array ‘a’ with all elements arranged in ascending order. Let low and high are the lower and upper indices of the array ‘a’, respectively. We want to search an item […]


Insertion sort in C program

Here is the program to sort the given integer in ascending order using insertion sort method. Please find the pictorial tutor of the insertion sorting. Logic : Here, sorting takes place by inserting a particular element at the appropriate position, that’s why the name-  insertion sorting. In the First iteration, second element A[1] is compared […]


Bubble sort program in C

Here is the program to sort the given integer in ascending order using bubble sort method. Please find the pictorial tutor of the bubble sorting. Logic :  The entered integers are stored in the array A. Here, to sort the data in ascending order, any number is compared with the next numbers for orderliness. i.e. […]


Mouse programming in C

Mouse can be used in text mode as well as in graphics mode. Usually it is used in graphics mode. Hence we must first change over to graphics mode. In our program the function initgraph() is responsible for switching the mode from text to graphics .DETECT is a macro defined in ‘graphics.h’. It requests initgraph() […]
