OpenCV数字图像处理十：读写txt文件，在图像训练和测试的时候经常用到

#include <cv.h>
#include <highgui.h>
#include <cvaux.h>


using namespace std;
using namespace cv;


bool showSteps = true;

#define dataNum ( 4381 )


int main()

FILE *fp;
int i,j;
if( ( fp=fopen("C:\\Temp\\negtives\\neg.txt","r") )==NULL ){
printf("can not open the file\n");
exit(0);
}


char *fileName = NULL;
fileName = (char *)malloc(dataNum*sizeof(char));

for(i=0;i<dataNum;i++){

//读取一行

fscanf(fp,"%s\n",fileName);
cout<<fileName<<endl;
} 

fclose(fp);

waitKey(0); 
}
