Test Using DFS Whether a Directed Graph -
This C++ Program checks whether a directed graph is weakly connected or not. We can do "DFS" V times starting from every vertex. If any DFS, doesn't visit all vertices, then graph

Using Virtual Functions in C++ Language -
See in this case the output is Woof, which is what we expect. What happens in this case? Since we marked the function animalSound() as virtual, the call to the function is resolved

Reads Input until Enters a Positive Integer -
C Language program to read input until user enters a positive integer. Positive Numbers 1, 2, 3... are known as natural numbers. C code below takes a positive integer (let say n) as...

Program Finds Sum of Digits of a Number -
'Sum of digits' means add all the digits of any number, we take any number like 358. Its sum of all digit is '3+5+8=16'. Using given code we can easily write c++ program. Enters any num

Program Prints Natural Numbers in Range -
Using above logic you can easily find a way to print natural numbers in range. If not here is a hint. Input start limit from user and store it in some variable say start. Input end limit from

C Programming Codes Multiply to Matrix -
Program code to multiply two matrices, the number of columns of first matrix should be equal to number of rows to second matrix. This c program displays the error until the...
