C + + One-pointer problem and resolution (char pointer garbled)

The whole problem

structnamegroup{Char*Name1; Char*Name2;};    Namegroup A () {namegroup result; //From the other DLL get values to Namegroup. //result. Name1 = source. Value1 result. Name2 = souce. Value2    returnresult;}//question↓voidB () {Namegroup Group=A (); printf ("Name1:%s", group.    NAME1); printf ("Name2:%s", group.    NAME2); //Name1: [Email protected]#[email protected]#//Name2: [Email protected]#[email protected]#}

The main point is to read the string data from other places, passed into the struct, and then outgoing.

In C # Of course there is no problem, recently in C + +, so that the final hit is garbled.

Later found that the string is the stack, a function execution end is destroyed, this time the structure of the pointer into a wild pointer, so it is garbled.

Solve:

Namegroup A () {    namegroup result;     // From the other DLL get values to Namegroup    . // result. Name1 = source. Value1 result. Name2 = souce. Value2    //result. Name1 = strcpy (result. Name1, source. Value1);     // result. Name2 = strcpy (result. Name2, source. Value2);    return result;}

Finally, add 2 lines to function A and copy the string to solve it.
