很简单的程序调试了近3个小时，每次调试都不知道怎么地退出了。
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char *LineBuf = NULL;
int BufLen = 0;
void PushToBuf(char c)
{
LineBuf = (char *)realloc(LineBuf, (BufLen+2)*sizeof(char));
LineBuf[BufLen] = c;
BufLen++;
LineBuf[BufLen] = '\0';
}
int main()
{
char temp[20];
int i;
FILE *fp;
fp = fopen("input", "r");
while (fgets(temp, 20, fp) > 0)
{
/*Push temp into buf*/
for (i = 0; i < strlen(temp); i++)
PushToBuf(temp[i]);
/*print buf*/
printf("%s\n", LineBuf);
printf("%d\n", BufLen);
/*make buf empty*/
free(LineBuf);
BufLen = 0;
}
return 0;
}

This is a test file, unimportant
