In this tutorial, we will be discussing a program to find the sum of the given series (1*1) + (2*2) + (3*3) + (4*4) + (5*5) + … + (n*n).For this, we will be given with the value of n and our task is to add up every term starting from the first one to find the sum of the given series.Example#include using namespace std; //calculating the sum of the series int calc_sum(int n) {    int i;    int sum = 0;    for (i = 1; i

In this tutorial, we will be discussing a program to find the sum of each row and each column for a given matrix.For this, we will be given with a say A*B matrix. Our task is to traverse through all the elements of the matrix and find the sum of each row and each column of the matrix.Example#include using namespace std; #define m 7 #define n 6 //calculating sum of each row void calc_rsum(int arr[m][n]){    int i,j,sum = 0;    for (i = 0; i < 4; ++i) {       for (j = 0; j < 4; ++j) {          sum = sum + arr[i][j];       }       cout

In this tutorial, we will be discussing a program to find the smallest element among the provided three elements.We will be provided with three elements/ integers and our task is to compare them and find the smallest element/ integer among them.Example#include using namespace std; int main() {    int a = 45, b = 72, c = 10;    if (a

In this tutorial, we will be discussing a program to find the side of the octagon inscribed within a given square.For this, we will be given with the side of a square and our task is to find the side of the largest octagon that can be inscribed in it.Finding the relation between the sides of the square and the octagon, we find the formula for the side of the octagonside of square/(√2 + 1)Example#include using namespace std; //calculating the side of the octagon float calc_oside(float a) {    if (a < 0)       return -1;   ...

In this tutorial, we will be discussing a program to find the rate percentage from compound interest of the consecutive years.For this, we will be provided with two integers say A and B that are the interests of two consecutive years. Our task is to find the rate of interest for the given values.Finding the relation between the given values and eliminating the principal amount, we get the formula asrate = ((B-A)*100)/AExample#include using namespace std; //calculating the rate of interest float calc_rate(int N1, int N2) {    float rate = (N2 - N1) * 100 / float(N1);    return ...

In this tutorial, we will be discussing a program to find the quantity of milk left after mixture replacement.Let us suppose we have X litres of milk. From that, Y litres of milk is replaced with Y litres of water itself. This same procedure is done again and again Z number of times. Our task is to find the final amount of milk left in the container.Finding the relation among the values between the repetitive operations, we find the formula for finding the amount of milk after Z number of operations to beamount left = ((X-Y)/X)Z*XExample#include using namespace std; ...

Given with the P number of processes in the memory and N number of needed resources by them to complete their execution and the task is to find the minimum number of resources R which should be allotted to the processes such that deadlock will never occur.What is a DeadlockDeadlock is situation in an operating system where multiple processes residing in the memory doesn’t able to perform their execution because the resources which are needed for program execution is being hold by another resource who is waiting for some other resource for completion.Let’s say there are two processes P1 and ...
