Expansion

Function: the output data is formatted into a string

Function prototype :

　　 int sprintf_s(

　　char *buffer,

　　size_t sizeOfBuffer,

　　const char *format [,

　　argument] ...

　　);

You need to include the header file: stdio.h

note:

         sprintf_s () is sprintf () version of security to avoid buffer length specified by sprintf () overflow risks

Program example:

filename char [ 1024]; // need to pre-allocate buffers

char path1[128] = "D:\\Program\\Tesseract-OCR\\tesseract.exe";
char path2[128] = "D:\\Program\\Tesseract-OCR\\";
char path3[128] = "D:\\Program\\Tesseract-OCR\\txt";
char path4[128] = "-l chi_sim";

sprintf_s(filename, sizeof( filename ), "%s %s %s %s", path1,filepath,path3,path4);

system(filename);
