C++ Implement Shortest Path Algorithm - For a general weighted graph, we calculate single source shortest distances in "O(VE)" time using 'Bellman-Ford Algorithm'. For a graph with no negative weights, we can do

Print some General File info in C program - Filename, device, inode, protection, number of hard links, user ID of owner, group ID of owner, device type, total size, blocksize for filesystem I/O, number of blocks allocated,

C Find Power of a number using Recursion - First give a meaningful name to our recursive function say pow(). The function must accept 2 numbers i.e. base. exponent and calculate its power. Hence, take 2 parameters for base

C Language Coding Print Alphabets a to z - Internally C represent every character using ASCII character code. ASCII is a fixed integer value for each global printable, non-printable characters. For example ASCII value of a=97,

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

Illustrate how User Authentication is Done - C programming code asks for the username, password and displays the same to illustrate user authentication. Take the user name and password as input. Print the each character...

Exception Handling Multiple Catch in C++ - In C++ code, 'Declare and define' the function test(). Within the try block check whether the value is 'greater than zero' or not. If the value greater than zero 'throw the value' and catch

Read integers into an array and Reversing - We have declared one pointer variable and one array. Address of first element of array is stored inside pointer variable. Accept Size of an Array. Now we have accepted element...
