在gcc中，写了这样几句代码
error: ‘for’ loop initial declarations are only allowed in C99 mode
这种for循环的写法在gcc中不支持，得现在for循环之前对i进行i定义，然后在使用
如果非得这么写的话在gcc进行编译的时候可以加上如下选项
note: use option -std=c99 or -std=gnu99 to compile your code
for(int i=1; i<=2; i++)
{
if(*e >= T[i])
{
*e = T[i];
}
}error: ‘for’ loop initial declarations are only allowed in C99 mode
