C++ Program to Display Factors of a Number





C++ Describe the Representation of graph - Takes the input of the 'number of vertex'. For each pair of vertex ask user whether they are connected or not. Print the adjacency matrix. A function to print the adjacency matrix. And

Whether a Path Exists Between two Given - We create a queue for BFS. Mark the current node as visited and enqueue it. It will be used to get all adjacent vertices of a vertex. Get all adjacent vertices of the dequeued vertex s. If

QuickSort For Files in The C Programming - First, create a file to sort, write unsorted data to disk and now, sort the file. Sorting disk file. A Quicksort for files. First read in record i and j and then write them back in opposite slots.

Program Convert Decimal to Hexadecimal - C Language Program code to take a decimal number as input and store it in the variable decimalnumber. Initialize the variable j=0 & copy decimalnumber to variable quotient.

C Code Rotate left rotate an Array n times - C program code to left rotate an array by n position. Logic to rotate an array to left by n position in C program. Read elements in an array say arr. Read number of times to rotate

Perform Exception Handling for Divide by - Declare the variables a,b,c. Read the values. Inside the "try block" check the condition. (a. if(a-b!=0) then "calculate the value" of d and display.b. otherwise throw the exception. So

C++ Programming Operators Precedence - "Operator Precedence" determines how an expression is evaluated. Some operators will have higher precedence than others. In this example, "Multiplication Operator" will have

Read and write Strings Printf() and Scanf() - Compare 2 strings, 'Concatenate Strings' and copy one string to another & perform various 'string manipulation operations'. We perform such operations using 'pre-defined' functions
