Hi Ahmed Ramzy

You can download Code::Blocks from here. 

If you use Windows an you have not yet installed Mingw,  you should download codeblocks-13.12mingw-setup.exe, otherwise download codeblocks-13.12-setup.exe.

If you use Linux, you'll probably find it in your repositories as codeblocks.

Otherwise search for your distribution binary here.

Install tesseract-ocr

For Windows https://code.google.com/p/tesseract-ocr/downloads/list download a installer and run it.

For Linux search in your repo's or download sources and compile it. For debian:

sudo apt-get install tesseract3 tesseract-ocr tesseract-ocr-eng

Start codeblocks, file>new>project.. empty project and Go.

Then, file>new>File.. chosse C++ and a name i.e. myocr.cpp

Then put in it:

#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>

int main()
{
    char *outText;

    tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
    // Initialize tesseract-ocr with English, without specifying tessdata path
    if (api->Init(NULL, "eng")) {
        fprintf(stderr, "Could not initialize tesseract.\n");
        exit(1);
    }

    // Open input image with leptonica library
    Pix *image = pixRead("/usr/src/tesseract-3.02/phototest.tif");
    api->SetImage(image);
    // Get OCR result
    outText = api->GetUTF8Text();
    printf("OCR output:\n%s", outText);

    // Destroy used object and release memory
    api->End();
    delete [] outText;
    pixDestroy(&image);

    return 0;
}

Then go to project->build options.. and linker settings tab. In Link libraries push add and put lept and then, add and put tesseract
