Advertisements I am a beginner in C and I am trying to copy a string inside another one. I have the following code: #include <stdio.h> #include <string.h> typedef struct { float mort_2009, mort_2015, indices; char estado[]; } Mortalidade; void defineEstados ( Mortalidade *e, char estado[], float mort_2009, float mort_2015, int posix) { strcpy(e[posix].estado, estado); e[posix].mort_2009… Read More Garbage printed with string after strcpy
Advertisements I am converting a character to a string by concatenating it with an empty string (""). But it results in undefined behaviour or garbage characters in the resultant string. Why so? char c = ‘a’; string s = ""+c; cout<<s<<" "<<s.size()<<"\n"; >Solution : Let’s look at your snippet, one statement or a line at… Read More Garbage when converting character to string using concatenation
Advertisements I’m trying to add some manual garbage collection at the end of my script, but for some reason when I iterate through dir() it is still picking up names that start with "blob" even though I’ve tried to specify not to do so. Reason for doing so is that trying to delete dataframes through… Read More If conditionals with not and startswith()
Advertisements I’m not talking about references to assemblies, rather the using statement within the code. For example what is the difference between this: using (DataReader dr = …. ) { …stuff involving data reader… } and this: { DataReader dr = … …stuff involving data reader… } Surely the DataReader is cleaned up by the… Read More C# What is the point of the using statement?
Advertisements I have this function, where I’m trying to return a const char*, but when I try to output the returned value, I get garbage value; virtual const char* what() const noexcept { std::stringstream s; if(m_id > -1) s << m_message << " with id " << m_id << " does not exist"; else s… Read More Returning const char* from funciton
Advertisements I would like to know if it is possible to in the first C program: Allocate and declare an int to the value of 5 in memory Print out the address of the variable (eg: 0x7ffee6a98ad8) Terminate And then in a second C program, after the first has completely finished executing: Read in the… Read More Is it possible to "create" garbage memory data in one C program, and then later read in that same data in from another C program?
