Like how to use them later

You can use a number just in cycle after its getting from std::cin, but if you want to use it subsequently, you can store them all to container. E.g.: int count{}; std::cin >> count; std::vector<int> numbers; for (int i = 0; i < count; ++i) { int number{}; std::cin >> number; numbers.push_back(number); }

Thanks

Next, you can get any value from vector numbers by this way numbers[0], numbers[1], numbers[2], etc

Thanks

It should be understandable to you if you have ever programmed in other languages

and how to make a loop that will check if number[1] > S, then it adds up with number[0], and if number[1] <S, then it skips it, and so on until the last number

I'm sorry if I bored you)

how to print

Print what? And where?

and how to make a loop that will check if number[1] > S, then it adds up with number[0], and if number[1] <S, then it skips it, and so on until the last number

If I understand you correctly, the past number must be added to each number, if each number is greater than S: for (int i = 0; i != numbers.size(); ++i) { if (i > 0 && numbers[i] > S) numbers[i] += numbers[i-1]; }

Thx

Thx

Be careful, the addition will be produced if each number is greater than S, but not if they're equal

how to print

😕 #include <iostream> int main() { std::cout << "Hello, world" << std::endl; }

pbuf1 = (char*)VirtualAlloc(NULL, // System selects address 100, // asks for 100 bytes MEM_COMMIT, // allocate committed memory PAGE_READWRITE); // protection = read and write printf("The first buffer allocated at : 0x%x\n", (DWORD)pbuf1); while (count < 100) *(pbuf1 + count) = 'a'; count += 1; //allocate the second the buffer pbuf2 = (char*)VirtualAlloc(NULL, // System selects address 100, MEM_COMMIT, PAGE_READWRITE); count = 0; printf("The second buffer allocated at: 0x%x\n", (DWORD)pbuf2); while (count < 100) *(pbuf2 + count) = 'b'; count += 1; //free buffers VirtualFree(pbuf1, 0,MEM_RELEASE); VirtualFree(pbuf2, 0,MEM_RELEASE);

it does not print the second buffer ?

😕 #include <iostream> int main() { std::cout << "Hello, world" << std::endl; }

i mean with the printer

i mean with the printer

Turn on

did it

it does not print the second buffer ?

Be more specific in your question

If I understand you correctly, the past number must be added to each number, if each number is greater than S: for (int i = 0; i != numbers.size(); ++i) { if (i > 0 && numbers[i] > S) numbers[i] += numbers[i-1]; }

Modified values of numbers are stored in your numbers vector

But… if I need to get the result in (sum2)

supposedly it should add up all the received numbers and write them down

Do you need to get the summary of all modified values in vector?

If I understand you correctly, the past number must be added to each number, if each number is greater than S: for (int i = 0; i != numbers.size(); ++i) { if (i > 0 && numbers[i] > S) numbers[i] += numbers[i-1]; }

Modify this code to (If I understand you correctly, again): int amount{}; for (int i = 0; i != numbers.size(); ++i) { if (i > 0 && numbers[i] > S) numbers[i] += numbers[i-1]; amount += numbers[i]; }

If you want to add only MODIFIED values, then put amount += line into if: int amount{}; for (int i = 0; i != numbers.size(); ++i) { if (i > 0 && numbers[i] > S) { numbers[i] += numbers[i-1]; amount += numbers[i]; } }

And the result will be written to (amount)?

cout << (amount)?

I want to write into this file: C++/HomeWorks/sodoku/board.txt I dont know what's wrong!?

any one plz!?

you better show the whole code

ofstream fout; char destinationFile[256]; string destinationFile = "C++/HomeWorks/sodoku/board.txt" if (fout.fail()) { cout << "Output file opening failed.\n"; exit(1); } else cout << "Board written successfully";

char destinationFile[256]; string destinationFile why and what is the reason?

you cant use duplicating variable name

error basically says the same

remove the second line

oh!! I see ... my bad

remove the second line

string

Friends who have apps are programming. I can bring the rap program to the top of the Play Store with Google Play's comment service. For service, visit Pewi.

you cant use duplicating variable name

If you still want to use destinationFile twice as variables, then change the case of one since c++ isn’t case sensitive

HW_3.cpp:331:12: error: conflicting declaration 'std::string destinationFile' 331 | string destinationFile = "C++/HomeWorks/sodoku/board.txt" | ^~~~~~~~~~~~~~~ HW_3.cpp:326:10: note: previous declaration as 'char destinationFile [256]' 326 | char destinationFile[256];

You have already declared it as char[256] before and you’re redecorating it… change the name of the variable.

ofstream fout; char destinationFile[256]; string destinationFile = "C++/HomeWorks/sodoku/board.txt" if (fout.fail()) { cout << "Output file opening failed.\n"; exit(1); } else cout << "Board written successfully";

By the way, if you declare a variable of concrete type (non-user-defined, such as char, int, float or any kind of arrays like your char[256]), you have to initialize it on its definition by default value. It prevents a lot of problems (caused by lack of default initialization and subsequently using of non-initialized variable with undefined value) while you’re beginner in language (you can make mistakes). Do like this: // code in some function int a{}; char c{}; char arr[256]{}; etc. It would be better to initialize even “user-defined” types, but you don’t have to do it: // code in some function string a{}; string b; // There is no difference between a and b However, you don’t have to do it, if you declared a variable in global namespace or specified it static. // global namespace int a; // good // any namespace static int b; // good

But the global or static part is in static memory, not stack afaik. And it's bad for multi threading

my copying array is 50 -1 90 so when l running through array l campare the next( for (i = 0; i <length-6; i++)) and previous ( for (j = 0; j < array2[i] - 1; j++)) elements

it's like buble sort

for (k = 0; k < array2[i]; k++) This line is rly strange. In your example this loop will repeat 50 times

for (k = 0; k < array2[i] here must be the length of array2, not an item in the strange position; k++) if (j > k) - what is the point in comparing indexes? You must compare items of array

Has anyone run into a case when vector fail to initialize with given initialize value by resize? I want to know it doesn't work.

I have a vector map and a enum class Grid, I want to initialize all the elements with map.resize(MAP_WIDTH, Grid::coin), but it doesn't work, and when I use for loop, it works.

what do you mean by that? On Windows there is exactly one System Process, usually with ID 4. Do you mean which processes have user mode parts? Or processes which have been started by the system?
