Depends on what you'r doing. May not need any specifically.

And Calculus has its uses in programming, but they aren't that many, relatively speaking. You'd be better off learning the basics of formal logic, combinatorics, and maybe a bit of statistics.

Calculus, physics, quantum physics, linear algebra and it's application is it important bro for learning c, c++ or for other programing languages? in university we have this classes it's mandatory in university

Discrete math and combinatoric

3.For each of the following, write a program that performs the indicated task. a)Declare the variable fptr to be a pointer to an object of type float. b)Declare the floating point variables num1 and num2. c)Assign 100.20 to num1 as initial value. d)Assign the address of variable num1 to pointer variable fptr. e)Print the value of object pointed to by fptr. f)Assign the value of the object pointed to by fptr to variable num2. g)Print the value of num2. h)Print the address of num1. i)Print the address stored in fptr.

anyone know how to solve this?

Has anyone read this book "Programming: Principles and Practice Using C++"? Did you find the exercises difficult?

anyone know how to solve this?

Just write the code

#include <iostream> using namespace std; int main() { float *fptr; float num1, num2; num1 = 100.20; fptr = &num1; cout << "*fptr=" << *fptr << endl; num2 = *fptr; cout << "num2=" << num2 << endl; cout << "&num1=" << &num1 << endl; cout << "fptr=" << fptr << endl; return 0; }

#include <iostream> using namespace std; int main() { float *fptr; float num1, num2; num1 = 100.20; fptr = &num1; cout << "*fptr=" << *fptr << endl; num2 = *fptr; cout << "num2=" << num2 << endl; cout << "&num1=" << &num1 << endl; cout << "fptr=" << fptr << endl; return 0; }

`num1 is undefined

`num1 is undefined

But it's defined

Hlo guyz! Actually, i'm the beginner for c++, so i wanna ask that what type of math is required for c++.

maths would help but it’s not necessary

But it's defined

Sorry, num2

#include<stdio.h> int main() { int son,son2,i,p; printf("Son kiriting:\n"); scanf("%d%d",&son,&son2); while(i=son && i<=son2) { p=sqrt(i); if(p*p==i) { printf("%d,",i); i++; } } } only shows the number 1 so help help me

As per your coad output should be 1

who can draw a 3d robot using OpenGL c++, please?

What do you mean "draw a 3d robot"? Just insert model into opengl program?

friend does not share any data among the classes. They are given access to private data of individual class by defining them as friend.

But if I want to do this code is correct?

const char *Jan1[][3] = {{"11","22","44"},{"55","77","88"},{"15","17","18"},{"16","17","18"}}; //4 const char *Feb1[][3] = {{"aa","bb","cc"},{"ee","ff","gg"},{"jj","kk","ll"},{"nn","oo","pp"},{"rr","ss","tt"}}; //5 const char *March1[][3] = {{"ww","xx","yy"}}; //1 // const char **ptx[3][4]= {*Jan1,*Feb1,*March1}; How to count internal child arrays of parent array with ptx ?

Thx bro

typedef struct { char name[50]; char matrixno[50]; float score[50]; }student; student std[100]; int main () { int k; int n=1; for (k=1 ; k<=n ; k++){ printf("Name: "); scanf("%s",&std[k].name); printf("Matrixno: "); scanf("%s",&std[k].matrixno); printf("Score: "); scanf("%f",&std[k].score); } printf("\n\n\n"); for (k=1 ; k<=n; k++){ printf("Name: %s\n",std[k].name); printf("Matrixno: %s\n",std[k].matrixno); printf("Score: %f\n",std[k].score); printf("\n\n"); }}

result of score is zero or adress num

there are libraries for developing web application but for moblie apps on android you are stuck with the java virtual machine

make sure you included the right header file

Hi! Please tell me how to fix "undefined reference to sqrt" in VS Code on Linux. I'm new to C / C++.

ohh.. on VScode try compiling it with gcc for C or g++ for C++ then if it compiles successfully just ignore the VScode warning

VScode sometimes give false alarms

include math.h

I did. It doesn't work. I searched Google for it and I didn't like those solutions.

#include "math.h"

how are compiling? use -lm flag

I'm using Ctrl + F5 for VS Code and F9 for Code Blocks.

That is a my code but when i enter 3 condision and try to diplay they can't show me but 1 and 2 condison visible.any solution

works fine, remeber to add a default contructor. Try it on other website, I did and it works

I'm using Ctrl + F5 for VS Code and F9 for Code Blocks.

it is just an issue of headers/libraries, try to compile it online or on other IDE

Thank you. It's strange that the error is in two IDEs.

send the code

smaller? it has too large, each F is 1111 and each 0 is 0000

nope. asembly

so it is in a register? or you read it from memory?

Do some research about Boost::Beast

i want to clear bit from 128 to 192 of 256 bit data

do it in integer way, 2^192 -2^128, that will give the number, you can use integer with assembly

use linux shell with g++ or clang

just use IDE on large project or to debug at memory level or something

to do simple projects is faster to code on sublimetext and compile with g++ directly

maybe is 193 and 127, I dont know, but you can get the point

For that reason I switched to micro text editor it is terminal based but let you use your mouse with autocomplete when you press the tab key and warnings and errors pulled directly from gcc when you save your C or C++ file by default

also it doesn’t use weird shortcuts for crtl+x to cut, crtl+v to paste crtl+c to copy crtl-q to quit the program with built-in terminal and you can use multiple tabs in addition many themes that is has by default also really useful when editing large files that crash VScode

micro sure easier than vim, but it's not IDE

I prefer visual studio. Much more comfortable

Visual studio has clang. And windows has WSL where you can use any Linux software.

I don't like Windows and other proprietary software. This is compromise to program in VS Code because it has dark mode.
