uninitialized local variable 'age' used. When you learn to better understand the error messages this actually has your answer. Based on your posted code the error is on line 16 not 13. You define int *age;, but
c:\src\test.cpp(10) : warning C4701: potentially uninitialized local variable 'p' used c:\src\test.cpp(10) : warning C4703: potentially uninitialized local pointer variable 'p' used 若要更正這則警告,請將變數初始化,如這個範例所示:

warning C6001: using uninitialized memory <variable> This warning is reported when an uninitialized local variable is used before it is assigned a value. This could lead to unpredictable results. You should always initialize variables before use. ...

.bss 段(Uninitialized Data) 用途:存放未初始化或初始化为0的全局/静态变量(如 int y; 或 static int z = 0;)。 特点: 不占用ELF文件的实际空间(仅记录长度),加载时由操作系统分配并清零内存。 提升存储效率(无需在文件中存储大量零值)。 .rodata 段(Read-Only Data) ...
The compiler applies stronger checks for use of uninitialized local variables of pointer type. When the new linker flag /HIGHENTROPYVA is specified, Windows 8 typically causes memory allocations to return a 64-bit address. (Prior to Windows 8, such allocations more often returned addresses that ...

warning: address of stack memory associated with local variable 'a' returned [-Wreturn-stack-address] 程序的输出如下: 100 但是,这个函数有隐患的,我们只要改一下主函数: intmain(){int*p=func();printf("%d\n",*p);printf("%d\n",333);printf("%d\n",*p);return0;} ...
