stable_sort() in C++ STL
The stable_sort method of STL first sorts the components with name as the key in ascending order and afterward the components are arranged with their segment as the key. Moreover, The stable_sort() calculation is viewed as steady in light of the fact that the overall request of comparable components is kept up. Here is the source code of the C++ program which exhibits the stable_sort() calculation demonstrated as follows;Example#include using namespace std; int main(){ int arr[] = { 11, 15, 18, 19, 16, 17, 13, 20, 14, 12, 10 }; int n = sizeof(arr) / sizeof(arr[0]); stable_sort(arr, arr + n); cout
Read MoreSorting string in Descending order C++
The sorting in ascending or descending order, however, can duly be performed by using string sort method and other means too in the C++ programming. But here, the string compare (first words with the second) and copy (copy the first word in a temp variable) method involved in the inner and outer traversing loop to put the words in descending order as following.Example#include using namespace std; int main(){ char str[3][20]={"Ajay","Ramesh","Mahesh"}; char t[20]; int i, j; for(i=1; i
Read MoreSort an Array of string using Selection sort in C++
The Selection Sort algorithm sorts an exhibit by more than once finding the base component from the unsorted part and putting it toward the start. In each emphasis of determination sort, the base component from the unsorted subarray is picked and moved to the arranged subarray.Example#include #include using namespace std; #define MAX_LEN 50 void selectionSort(char arr[][50], int n){ int i, j, mIndex; // Move boundary of unsorted subarray one by one char minStr[50]; for (i = 0; i < n-1; i++){ // Determine minimum element in unsorted array ...
Read MorePrinting Pyramid in C++
This article yields a “pyramid-like structure” as an output using the C++ programming code. In which the pyramid height and space are being determined by traversing double for loop constructs as following;Example#include using namespace std; int main() { int space, rows=6; for(int i = 1, k = 0; i
Read MorePrinting Different pattern Bash in C++
This article is intended to print a half-pyramid pattern bash using the C++ programming language. In the view of the stipulated pattern to be printed, the following algorithm is being orchestrated to achieve our goal as;AlgorithmStep-1 Set the length of the Bash (Height) Step-2 Outer loop to handle the number of rows Step-3 Inner loop to handle columns Step-4 Print the pattern with the character (@) Step-5 Set the pointer to a new line after each row (outside the inner loop) Step-6 Repeat the loop till the Bash HeightExampleSo, the following C++ source code is ultimately carved out by complying ...
Read MoreToggle all characters in the string in C++
This program translates the characters of a string into uppercase. However, this task can be easily achieved by using the toUpper() method of the c++ class library. But in this program, we perform this by calculating the ASCII value of characters in uppercase. The Algorithm is as follows;AlgorithmSTART Step-1: Declare the array of char Step-2: Check ASCII value of uppercase characters which must grater than A and lesser than Z Step-3: Check ASCII value of lower characters which must grater than A and lesser than Z ENDThe toggleChar() method gets the array of characters as an input. ...
Read MoreSwap Upper diagonal with Lower in C++
This tutorial is designed to swap the upper row of a three-diagonal array to its lower one using c++ code. Moreover, if a three-diagonal array is an input, the coveted results must be something like that as;For this, the course of action is briefed in the algorithm as follows;AlgorithmStep-1: Input a diagonal array Step-2: Pass it to Swap() method Step-3: Traverse the outer loop till 3 Step-4: increment j= i+ 1 in the inner loop till 3 Step-5: put the array value in a temp variable Step-6: interchange the value arr[i][j]= arr[j][i] Step-7: put the temp data to arr[j][i] Step-8: ...
Read MoreSqrt, sqrtl, and sqrtf in C++ programming
Math ClassThis article demonstrates the usage of math class essentials functions sqrt(), sqrtl(), and sqrtf() to calculate the square root of double, long, and float type variables with precision respectively. The Math class of C++ offers a wide range of functions to calculate mathematical calculations including sin, cos, square root, ceil, floor, etc..It is, therefore, mandatory to import the definition of header class library in the program in order to avail all calculative methods.Sqrt MethodThe double sqrtl () method of the Math class returns the square root of a double variable with precision. The syntax of this function is ...
Read MoreReplacing space with a hyphen in C++
In this C++ program, the space in the string will be replaced with the hyphen. Firstly, the length of the string is determined by the length() function of the cstring class, then hyphen is filled into the space of the sentence by traversing the string as follows.Example#include #include using namespace std; int main(){ // raw string declaration string str = "Coding in C++ programming"; cout
Read MoreValidate IP Address in C++
This article is serving the purpose of validating the correct IP (internet protocol) address by virtue of C++ code programming. The IP address is a 32-bit dot-decimal-notation, broken into four decimal numbers segments ranging from 0 to 255. Furthermore, these numbers are separated by dots consecutively. The IP address serves the purpose of identifying a host machine in the network in a unique manner in order to establish a connection among them.So, in order to validate the correct IP address input from the user-end, the following algorithm briefs how exactly the code sequence is materialized to identify the correct IP ...
