what the output actually should be?

What is the logic behind putting #x, I dont think it is correct.

stringizing.

#include <iostream> using namespace std; #define MKSTR ( x ) #x int main (){ cout << MKSTR (HELLO C++) << endl; return 0; }

#include <iostream> using namespace std; #define MKSTR ( x ) #x int main (){ cout << MKSTR (HELLO C++) << endl; return 0; }

what error are you getting?

#include <iostream> using namespace std; #define MKSTR ( x ) #x int main (){ cout << MKSTR (HELLO C++) << endl; return 0; }

<stdin>:6:13: error: use of undeclared identifier 'x' cout << MKSTR (HELLO C++) << endl; ^ <stdin>:4:17: note: expanded from macro 'MKSTR' #define MKSTR ( x ) #x ^ 1 error generated.

by any chance do you have a space between MKSTR and (x) ?

bool func(int x) { if (x==2) return true; else return false; } ------------------------ bool func(int x) { if (x==2) return true; return false; } Is there any difference between these two other than the structure?

No difference. You can compile them to see the assembly code. They are the same.

tnx, how can I see the assembly code?

tnx, how can I see the assembly code?

i also ever saw one online compiler which could compile to high level source only 🤔 I forgot what is it

What means compile to high level source? Did you mean decompile or IR?

Compiler Explorer is good, too. https://godbolt.org/

tnx, how can I see the assembly code?

compile using command: gcc -s yourcode.c -o yourassembly.s

hmmm i think transpiling it to assembly

it show's a red highlighting in one line, what does that mean ?

Whats red highlight? If you mean the colorful highlight, the cpp code of the same color corresponds the assembly code of the same color.

ohh kk. 😅 I thought it was some kind of error.

Hello please help 👆👆👆

I don't usually send code for someone else to see and correct it, because I try to figure it out by myself but I have been trying to debug this one for hours now, it's simple but somehow it's not working. My code: https://pastebin.com/kfb1yMFB Question: https://www.spoj.com/problems/MIXTURES/ If anyone can help me out, it'd be great. Thanks in advance.

Your DP equation seems wrong. The DP array should store the mininum smoke generated for a range. What purpose does csum solve if you are again going to be adding them all sequentially? Please clarify this.

i am adding them in csum but they should be multiplied too - cuz matrix chain multiplication

Yeah it seems right. Let me check again.

Hello am need help in order to learn more about c++ programming

Can anyone share the best website for STL

please learn some keywords of algorithms. and search features with google

you can also learn some scripting language to see what problems are common

SQL?

This code gives me the error: conflicting types for 'readMatrix' in line 31

You figured out the issue with your code? I just changed 2 lines and it worked fine and the answer was also accepted. Previously I was just trying to understand your code on my phone and your macros kept me running in circles. But once I got home, I just loaded it on my system, changed 2 lines and submitted the solution on SPOJ to see if it was fine. It was.

I changed the line using scanf to while(cin >>n) I then replaced the call to memset with the 2 for loops below it. The problem is that memset interprets the 2nd parameter (int)as an unsigned char. So the value -1 is interpreted as 255.

Hold up At first I did it without memset and it wasn't working either :0

I just submitted the solution and it was accepted. Not sure why yours is getting rejected then. Check out ID = 28128919 in the submitted solutions

Given the following numbers (23, 45, 2, 6, 56, 7, 8, 49) write a program which will store these numbers into an array and display them in ascending order. Plz help me

Hello everyone Why i can't copy strcpy(matriz[fila] [columna] , pieza) "matriz" is char type and "pieza" is a variable that i saved a character before (char type too) I get this message: Invalid conversion from 'char' to 'char*' Help me please :(

https://www.man7.org/linux/man-pages/man3/strcpy.3.html

Ohh must to be constant not variable Thanks bro i will have to find out other way to do that 😢

Noooooo. That is not the issue. strcpy is used to copy strings (null terminated) and not a char.

I got it, the solution was this: pieza=getch() and then i saved the variable like this matriz[fila][columna]=pieza 😂 Anyway thanks so much for answer bro

is possible compare values between two std::map?

Yeah, I was confused about this some days back Simply used "==" to compare.

i search the difference
