Given with n numbers program must find those n number whose sum is a perfect squareInput : 5 Output : 1 3 5 7 9 1+3+5+7+9=25 i.e (5)^2AlgorithmSTART Step 1 : Declare a Macro for size let’s say of 5 and i to 1 Step 2: loop While till i printing (2*i)-1 Step Step 2.2 -> incrementing i with 1 Step Step3-> End loop While STOPExample#include # define SIZE 5 int main() { int i=1; while(i
Here we will see how to write one-line C function, that can round floating point numbers. To solve this problem, we have to follow these steps.Take the numberif the number is positive, then add 0.5Otherwise, subtract 0.5Convert the floating point value to an integer using typecastingExample#include int my_round(float number) { return (int) (number < 0 ? number - 0.5 : number + 0.5); } int main () { printf("Rounding of (2.48): %d", my_round(2.48)); printf("Rounding of (-5.79): %d",my_round(-5.79)); }OutputRounding of (2.48): 2 Rounding of (-5.79): -6
This is a C++ program to generate all pairs of subsets, whose union make the Set.AlgorithmsBegin function UnionSet(): Arguments: a[] = an array. n = number of elements. Body of the function: 1) Generate binary code from 0 to 2^(n-1)-1 for all 2^(n-1) pairs. 2) Print the array element which has 0 or 1 in corresponding indexes in code string for each code. 3) Print them in a different set, which on the union of both sets gives the super set. EndExample#include #include #include using namespace std; void display(char code[], int a[], int n) //display the pairs { int i; cout
To create a user in MongoDB v3, use the createUser() method. This allows you to create a user and while creating you need to add user, password, and roles as well. These roles assign permissions. The syntax is as follows −use admin db.createUser( { user: “yourUserName", pwd: "yourPassword", roles: [ { role: "yourPermission", db: "yourDatabase" } ] } );Let us implement the above syntax in order to create a user In MongoDB v3 −> use admin switched to db admin > db.createUser( ... { ... ...

Clear to Send (CTS) is a control frame employed in the medium access control (MAC) layer protocol IEEE 802.11 RTS/CTS. The protocol uses the concept of Multiple Access with Collision Avoidance (MACA) in wireless networks. The RTS/CTS (Request to Send / Clear to Send) mechanism aims to reduce frame collisions introduced by the hidden terminal problem. CTS frame is sent by the receiver after it gets the RTS frame prior to receiving of the actual data frame.Working Principle of MACA implementing CTSThe MACA protocol works with the condition that the communicating stations are synchronized and frame sizes and data speed ...
