Find First and Second Biggest In An Array, Without Sorting It: C
We assume that a[0] has first biggest and a[1] has the second biggest value. Now check if this assumption is correct, if not, swap the values. if( sbig > fbig ) { temp = sbig; sbig = fbig; fbig = temp; } Now since we have already checked with a[0] and a[1], we start [...]

Find Biggest In An Array, Without Sorting It: C
First we have to assume that a[0] is biggest. Now store the value of a[0] inside a variable called big. Now compare value of big with other values in the array. If big is less than any other value, then store the bigger value inside variable big. Video Tutorial: Biggest In An Array, Without Sorting [...]

Bubble Sort: C
In this video tutorial we illustrate the bubble sort algorithm and also see how to write it in C programming, for 5 elements as well as to N elements. In bubble sort, a[0] is compared with a[1]. a[1] with a[2], a[2] with a[3] .. so on if a[0] is greater than a[1], the values are [...]

Selection Sort of N numbers: C
Selection sort is a sorting technique which is inefficient on large list of elements. Its simple and easy to understand. In selection sort, first we select one element and compare it with the rest of the elements. If the compared element is smaller than the selected element, then those numbers are sorted. This approach is [...]

Find the Factorial of a Number: C
This video tutorial illustrates finding factorial of a given number using C programming. In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. Ex: if user enters 5, then the factorial is 1 * 2 * 3 * 4 * [...]

Find Given Number Is Prime or Not: C
A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 7 is prime, as only 1 and 7 divide it, whereas 10 is [...]
