Hi, Im using dev c and I cant use the stoi function and I kinda need to use it. I searched how to fix that problem in google but it doesnt seem to work. Is there an alternative way to have the same function as stoi. I cant use atoi because i want to convert a string and atoi requires const char. to be used.
thanks for your concern .. I AM QUITE KEEN TO MAKE SOME PROGRESS IN INFORMATICS OLYMPIAD AND ACM-ICPC BUT ALL THESE TECHNICAL YET NON-ALGORITHMIC PROBLEMS ARE POSING A BIG PROBLEM by the way if u just have time the competition website is http://www.iarcs.org.in/inoi/about_gcc.php or just just google ' inoi ' its the first result Switching from Turbo C++ to gcc/gpp: Some common problems IARCS home > OLYMPIAD > Current Do not use #include <conio.h> You will not need any functions from this header (e.g., clrscr(), getch()). Note: The Dev-C++ and Code::Blocks compilers are based on gcc, but both of them allow some non-gcc header files, notably conio.h. Please rememmber not to use conio.h, otherwise your programs will not compile under gcc on the evaluation server. For C++ header files such as iostream.h, leave out the suffix .h when including the file. That is, use #include <iostream> rather than #include <iostream.h> Note: The does not apply to C header files such as stdio.h. For C header files, include the suffix .h, as usual. For example: #include <stdio.h> After the header files, add the line using namespace std; to ensure that C++ finds the functions cin and cout. Define main as int main() rather than void main(). To summarize, here is how a typical C++ program using gcc/gpp would look: #include <iostream> using namespace std; int main(){ cout << 'Hello worldn'; } this is what that site says MY DEV C++ IS FROM ORWELL , LIKE I SAID I KNOW VERY VERY WELL WHAT DOES A BASIC HELLO WORLD PROGRAM LOOK LIKE IN TURBO C++ AS WELL AS WHATEVER THIS GCC /ANSI /MINGW (I DONT KNOW WHAT TO CALL THIS VERSION WHERE using namespace std; is compulsory) BUT THATS WHAT MY PROBLEM IS THE EXE BLACK SCREEN STAYS BLANK (NOT UNRESPONSIVE IT CAN BE CLOSED WITH (ALT +F4) BUT NO OUTPUT AT ALL NOR THERE IS ANY DIAGNOSTIC STATEMENT ) THIS PROBLEM REPEATS AFTER EVERY 10 DAYS SO, I REINSTALL THE COMPILER AGAIN N AGAIN AND RECACHE ALL HEADER FILES THEN THE PROBLEM IS RECTIFIED THANKS AGAIN
Dev C Not Launching Video
Okay this is a first for me. My code compiles absolutely fine with no errors what so ever. But when I click 'Run' or 'Compile & Run', the little command window pops up but the output never appears? The command window tries to load the code for about 5 seconds and then it gives up, when usually it takes about 1 second to see my output. After it tries to load, the command window stays scrolled down all the way at the bottom. Usually the code appears at the very beginning of the command window, so when I tried to scroll up, the side bar immediately pulls itself down. I have made 9 different programs over the past 5 months and every single one of them runs fine except this one. What I am doing in my code, is creating a class. This class is using methods to add, subtract, and multiply matrices. Assuming my code is fine, why is Dev C++ doing this? I'd post my code, but it compiles without a hitch and it's 300+ lines of code. I'm sure nobody wants to read that much into this. Does anyone know why this happening? P.S. I don't even get the 'Press any key to continue..' that usually appears after your output in the command prompt window, even after waiting five minutes.
