Not sure why I am getting an error here

I did some more debugging and im running into an error at this section of my code. This is the error i got, im not sure why. I think it might be because im not storing the values to the dynamic memory properly.

im still getting the same error

i didn't sleep last night so sorry if i'm missing something but i don't think your if condition makes sense

If the title and mark are both NULL (missing), then store and allocate them? try just setting the result of the read functions to a boolean and then use that as the condition

RevanOP•3y ago

yeah this is what i did orignally but i still got an error

c++
bool doubleRead = read(localDble, fptr);
bool charRead = read(localChar, fptr);
// ...
if(doubleRead && charRead) {
    //...
}

c++
bool doubleRead = read(localDble, fptr);
bool charRead = read(localChar, fptr);
// ...
if(doubleRead && charRead) {
    //...
}

that block looks okay to me, can i see the actual m_mark when you first assign it?

c++
//new char[cStringSize];
new char[strlen(localChar) + 1];

c++
//new char[cStringSize];
new char[strlen(localChar) + 1];

the size of the string is not consistent and the memory is dynamically allocated so i think you have to do it like that i think this can just be

c++
//new double [n]
new double;

c++
//new double [n]
new double;

c++
//Asm.m_mark = &localDble;
*Asm.m_mark = localDble;

c++
//Asm.m_mark = &localDble;
*Asm.m_mark = localDble;

ok now i can go throug the loop one time but at the second iteration it breaks

The Many•3y ago

hmm. check how it's counting up i guess. i have to run
