true means function is on and false means function is off and 0 == off

0 means successful termination that's because 0 means off

Why return 0 signifies successful termination whereas anything other than zero unsuccessful termination? Asking in reference to the general terminology that 0 is false and non zero is true?

Because any other number can be an error code and 0 means that no error code was thrown which is success. It's UNIX standard

Is it really a Unix standard or is it just POSIX thing?

As I know it's a UNIX standard but maybe I am wrong, you can use Internet for finding out

It just doesn't make sense to me that why others would be using Unix standard... That was it

Why not? Standardisation through different things is something that is very convenient for programmers and users

I need to make CreateRandomArray and FindMax methods, but I don't know how to help #include <iostream> #include <cstdlib> using namespace std; const int N = 100; int main() { int mass[N], max; cout << "Elements: "; for (int r = 0; r < N; r++) { mass[r] = rand() % 99;//CreateRandomArray cout << mass[r] << "|"; } cout << endl; max = mass[0]; //FindMax for (int r = 1; r < N; r++) { if (max < mass[r]) max = mass[r]; } cout << "Max: " << max << endl; return 0; } its c++

At first Your max must be Max=0;

Hi. You can write and run codes of c++ in Turbo C++, Dev c++, code block, Microsoft visual C Plus.....

i recommend dev c++ because of its ease of installation and use

At first Your max must be Max=0;

I'm just worried

Mr. Karun wants to implement an automated system to compute the factorial of a given number. Where Karun has studied the concept of factorial of a number in mathematics. Help him to implement the same in C Language and check the obtained factorial number is even or odd. If the obtained factorial is even the print Even Factorial else Odd Factorial.

Use recurssive function. This is not complicated one. U can easily write code on your own if U spend little bit time. Logic is your instinct. If U find problem with understanding syntax post it here.

Please send code

Write a function that uses pointers to search for the address of an assumed integer in an array. If the assumed number is found, the address function takes it and otherwise returns nullra ?????

Write a function that floats n pointers and returns an array that contains n floats.???????

Floats pointers? What?

n Pointer to receive float

did you understand how pointer works ?

In fact no

Start learning step by step .. dont try to jump to the results ..

Well, you can only answer these questions for me

You didnt even ask. You typed some words and put question marks after them.

Can I send a personal message to Weston and help me?

What?

Yes

Who is Weston?

use %zu next time to print value from sizeof operator

in code size of struct allowed 13 byte but it shows 16 to struct

#include<iostream> #include<fstream> #include<string> using namespace std; int main() { string inputFile, outputFile; //prmpt user for input file cout << "Please enter a file name for input file: "; cin >> inputFile; //open file to write content ofstream inFile(inputFile); Why cannot use ofstream inFile(inputFile); ???

Do you add the the file extension?? ie. cin >>inputFile hello.txt

#include<iostream> #include<fstream> #include<string> using namespace std; int main() { string inputFile, outputFile; //prmpt user for input file cout << "Please enter a file name for input file: "; cin >> inputFile; //open file to write content ofstream inFile(inputFile); Why cannot use ofstream inFile(inputFile); ???

Try to write full file path in the input

Okay thank you ☺️
