TXT文件中为一行数据21 23 34，如何用MFC读取这三个数据并分别赋值给a,b,c？

Answer 1

c++、、

Answer 2

#include <stdio.h>
#include <stdlib.h>

int trans(char a,char b);
void main()
{
char a,b,c;
FILE *fp;
fp=fopen("c:\\tom.txt","rb");
char *num=new char[9];
int i;
for(i=0;i<9;i++){
fread(&num[i],sizeof(char),1,fp);
}
a=trans(num[0],num[1]);
b=trans(num[3],num[4]);
c=trans(num[6],num[7]);
printf("a=%d b=%d c=%d",a,b,c);
delete num;
fclose(fp);
getchar();
}
int trans(char a,char b)
{
int sum;
sum=((a-'0')*10)+(b-'0');
return sum;
}
