    SDL_ttf Process terminated with status 3

    Hello guys, I am creating a very simple game. I have used SDL and Everything works fine, but whenever I try to use SDL_TTf to print scores, Programs terminates with process status 3. Without SDL_TTF code, everything works. Here is the code :-

    Code:
    #include <iostream>
    #include <cstdlib>
    #include <SDL/SDL.h>
    #include <SDL/SDL_ttf.h>
    #include <sstream>
    
    const int WINDOWS_Height = 480;
    const int WINDOWS_Width = 640;
    const int SPRITE_SIZE = 32;
    const int BALL_SIZE=15;
    const char* WINDOWS_Title = "Ball Collecting Game";
    
    using namespace std;
    SDL_Surface *grass, *sprite, *temp, *ball, *scores;
    SDL_Rect rcSprite, rcGrass, rcSrc, rcBall, rcScores;
    int colorkey, score=0, bc=0;
    bool runGame = true;
    stringstream pScore;
    
    bool checkCollision(SDL_Rect Sprite1, SDL_Rect Sprite2);
    void handleEvents(SDL_Event event);                                                                 // Function to handle Events
    
    int main (int argc, char *argv[]){
        SDL_Init(SDL_INIT_VIDEO);                                                                                // Initializing SDL and Creating Window

    > times = TTF_OpenFont("Lato.ttf", 10);
    You need to check whether this is NULL or not.
    If it is NULL, then you didn't get the font you wanted.

    Also, it's a good idea to write another program which just tests the font aspect.
    In essence, the "hello world" version of the problem you're trying to write.

    Writing small test programs to make sure you understand a problem completely is a useful technique.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Thank you Salem,
    Problem is resolved but now as I touch the ball score not clears. I want to be score like this.
    10
    20 (after a ball is collected) and so on, but it goes something like this 10
    1020(after a ball is collected).

    Thank you again.


    problem Solved .....
    Just have to empty pScore before reassigning.

    Why my .exe not working outside Codeblocks?

    Perhaps it has a different idea as to what the "current directory" is.

    So when you do this
    temp = SDL_LoadBMP("sprite.bmp");
    It will always look in the "current directory".

    IIRC, double clicking on a .exe in explorer makes the current directory the location of the .exe
    Within the IDE, it could be just set to the project root.

    I have already changed all of them from "sprite.bmp" to "./sprite.bmp".
