按照空格读取文件

#include <stdio.h>
main()
{
 char s1[20] = {0};
 char s2[20] = {0};
 char s3[20] = {0};
 int i=0;
 FILE *fp;
 fp = fopen("log.txt","r");
 fscanf(fp,"%s",s1);
 fscanf(fp,"%s",s2);
 fscanf(fp,"%s",s3);
 printf("%s\n%s\n%s\n",s1,s2,s3);

}

#

#

#

代码二：

#include <stdio.h>
main()
{
 char s[10][20] = {0};
 int i=0;
 FILE *fp;
 fp = fopen("tmp.txt","r");
 for(i=0;i<3;i++)
 {
  fscanf(fp,"%s",s[i]);
  printf("%s\n",s[i]);
 }
}
