软件为CLion。
功能需要从文件中读取整数浮点数和字符串,按照书上写的fscanf函数。代码如下
#include <stdio.h>
int main()
{
FILE *open;
open=fopen("test.txt","w");
int i=123123;
fprintf(open,"%d",i);
printf("%d",i);
fclose(open);
open=fopen("test.tst","r");
fscanf(open,"%d",&i);
printf("%d",i);
fclose(open);
return 0;
}
运行后没有输出,只有一行报错
Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)
把fscanf那行注释掉就可以正常输出。
可能是我理解不够透彻,望各位不吝赐教,或者有更方便地读取方法用来替代也可以
