Question

我想我把C语言产生的数组给存到文件中去，并且每个数据以空格隔开怎么弄

存储的文件要在matlab里用

Answer 1

#include "stdio.h"
#include "string.h"

void log(int data[],int);

#include "stdio.h"
#include "string.h"

void mlog(int data[],int);

int main(){
int data[10]={1,2,3,4,5,6,7,8,9,10};
mlog(data,10);
return 0;
}

void mlog(int data[],int data_size){
FILE * fp;
int i=0;
char tmp[20];
if((fp=fopen("data.txt","a+"))!=NULL){
for(i=0;i<data_size;i++)
{
sprintf(tmp,"%d ",data[i]);
fputs(tmp,fp);
}

fclose(fp);
}else{
printf("can't open log file");
}

}
