C++ Language Character & String Literals -
When writing both single "character & string" literals, it is Necessary to 'Put the Quotation' marks surrounding them to distinguish them from possible variable identifiers or reserved

Remove last Occurrence of Character from -
C program to 'Read any String' from user and Remove Last Occurrence of a given character from the string. Remove last Occurrence of a character from the string. Shift all characters

C++ Multiply Two Matrices use 2D Arrays -
C++ Code is very simple it takes input in two 2D arrays each with size of 2X2. After taking the input program "multiply two matrix" in 3 nested for loops. Size of arrays is defined use

Checks the Connectivity of Directed Graph -
Add Edge to connect "v" and "w". A recursive function to print BFS starting from s. Returns reverse ('or transpose') of this graph. Check if graph is connected. Print graph is connected.

C++ Language Implements Binomial Heap -
Linking nodes in binomial heap. Create nodes in binomial heap and Insert nodes in binomial heap. Union nodes in "Binomial Heap". Merge nodes in binomial heap. And display binomial

C Program Codes Finds Area of Trapezium -
C Language program to calculates the area of trapezium. The Formula used in this program are Area = (1/2) * (x + y) * h where x and y are the Two Bases of Trapezium & h is the height.

C Find Volume and Surface Area of Sphere -
C Program calculates the volume and surface area of sphere. The formula used in this code Surface_area = 4 * Pi * r2, Volume = 4/3 * Pi * r3 where r is the radius of the sphere, Pi= 22/7

Swaps Array Elements and Reverse Arrays -
Program declare an integer array of size five, initialize it using for loop. Pass size and array name to function. Function uses for loop and "swap array elements" with in it. A for loop is
