Good evening How do I check if an input is an integer Thanks

You can check if it is digit or you can try converting it with a check

What about isdigit()?

can someone help me with this: CI = p * (pow((1 + r / 100), t)); how should i change the formula if i want to find r?

Thank you!

#include <Windows.h> #include <iostream> int nScreenW = 120; int nScreenH = 30; int main() { wchar_t* screen = new wchar_t[nScreenW * nScreenH]; for (int n = 0; n < nScreenW * nScreenH; n++) { screen[n] = L' '; } HANDLE hConsole = CreateConsoleScreenBuffer(GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL); SetConsoleActiveScreenBuffer(hConsole); DWORD dwBytesWritten = 0; int i; while (true) { for (i = 0; i < nScreenW * nScreenH; i++) { screen[i] = 0x2588; } WriteConsoleOutputCharacter(hConsole, screen, nScreenW * nScreenH, { 0, 0 }, &dwBytesWritten); } return 0; }

Ask in Microsoft programming forums or Stackoverflow. Don't see many Windows related questions being answered here.

I solved it thanks anyway

Hello All, I am trying to access shared file from another computer system on same network. i wrote c++ code for testing it worked completely fine but when i tried to run same code in my software I am getting file size as (-1) and error is permission denied What is reason for it and how to fix this?

Random_number=rand()%max+min;.. Random_number=rand()%(max-min+1)+min;..... Whats the difference between them???

Hello guys, I'm a beginner in programming and currently struggling with one task, if someone could help me, I'd very thankful (c++)

hi eveyone, now xmake has supported c++20 modules and analyze inter-module dependency compilation, and parallel compilation optimization welcome to try it. https://github.com/xmake-io/xmake/wiki/xmake-v2.5.9-released,-Improve-Cplusplus20-Modules-and-support-Nim,-Keil-MDK-and-Unity-Build

#include <iostream> using namespace std; struct Person{ int age; struct Person*link; }; void addAtEnd(Person *head, int x) { Person *temp= new Person; temp->age=x; temp->next = NULL; // Person *ptr= head; while(ptr->next !=NULL) ptr = ptr->next; // ptr->next=temp; } int main(int argc, char** argv) { Person *head= new Person; head->age=23; head-> next= NULL; // addAtEnd(head,24); addAtEnd(head,25); addAtEnd(head,26); return 0;

what is wrong with code

#include <iostream> using namespace std; struct Person{ int age; struct Person*link; }; void addAtEnd(Person *head, int x) { Person *temp= new Person; temp->age=x; temp->next = NULL; // Person *ptr= head; while(ptr->next !=NULL) ptr = ptr->next; // ptr->next=temp; } int main(int argc, char** argv) { Person *head= new Person; head->age=23; head-> next= NULL; // addAtEnd(head,24); addAtEnd(head,25); addAtEnd(head,26); return 0;

what is struct Person*link; shouldn't it be struct Person* next;

Hi everyone can someone help me with this 🙏🏻🙏🏻 Create a c program that will perform the given below using array, conditional statements and loops. -input 5 grades in an array -determine if the input grade is passed of failed -then count how many grades are passed or failed

int main() { int Grades[5]; int gradespassed = 0; int gradesfailed = 0; for(int i = 0; i <5; i++){ printf("Enter Grade %d:", i+1); scanf("%d", &Grades[i]); } printf("\n"); // Since Pass Grade was not Specified , everything above 39 is a Pass mark here for(int i =0; i <5; i++){ if (Grades[i] > 39){ printf("Grade %d: Passed!\n",Grades[i]); gradespassed ++; } else { printf("Grade %d: Failed! \n", Grades[i]); gradesfailed++; } } printf("\nGrades Passed are %d.", gradespassed); printf("\nGrades Failed are %d.", gradesfailed); return 0; }

int main() { int Grades[5]; int gradespassed = 0; int gradesfailed = 0; for(int i = 0; i <5; i++){ printf("Enter Grade %d:", i+1); scanf("%d", &Grades[i]); } printf("\n"); // Since Pass Grade was not Specified , everything above 39 is a Pass mark here for(int i =0; i <5; i++){ if (Grades[i] > 39){ printf("Grade %d: Passed!\n",Grades[i]); gradespassed ++; } else { printf("Grade %d: Failed! \n", Grades[i]); gradesfailed++; } } printf("\nGrades Passed are %d.", gradespassed); printf("\nGrades Failed are %d.", gradesfailed); return 0; }

If there’s a built in function to detect the size of the array then use that

I think the question already gave the size of the array Maybe i don’t get what you mean so if you could explain further

for (int i = 0; i < sizeof(grades); i++

What is .CPP and .h files in c++. What is header guards and how it useful?..could someone help me

.cpp is the file where you write all your functions or programs in c++ language

.h is a file which contain declarations of functions related to something, you can use for example a math header "math_functions.h" file where you declare functions as multiplication, add, power, etc

Implemtation of methods..
