函数功能:将数据格式化输出到字符串
函数原型:
int sprintf_s(
char *buffer,
size_t sizeOfBuffer,
const char
*format [,
argument] ...
);
需要包含的头文件:stdio.h
注意:
sprintf_s()是sprintf()的安全版本,通过指定缓冲区长度来避免sprintf()存在的溢出风险
程序示例:
char filename[1024];//需要预先分配缓冲区
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,"%s %s %s %s",path1,filepath,path3,path4);
system(filename);
