Suppose i write,
char **p;
p[0] = strdup("hello");
Strdup creates a duplicate string in heap with ending character '\0'; As p is pointer to pointer of char, p[0] = strdup("hello") seems perfectly fine for me. But why am i getting segmentation…
I am having the following error when I run Valgrind, I tried to free all the used functions, but still have the same error message

When i try run with the reviews.csv file the code gives segmention

guião1v2.h only are the structs made for this. In the code i add
some comments for being much easier understand what i'm…
We are having a 'Entry' class like below and std map with set of Entries. at the end we clean the map but valgrind shows possible leaks of the memory allocated via strdup function.
class Entry
{
public:
char* m_key;
t m_data;

I have designed for Huffman tree convert binary code with shorter bin code. In main if you call a Binary tree.init(q), then the tree would come out with key: frequency and value: bin code. The problem is converting const char* with char*. I've…
I'm having some issue with my stack implementation, my push function manipulate the value i send into the function and changes it. I have tried diffrent ways of constructing this but they either don't work or give me corrupted output.

In this case I'm trying to understand the difference between this wrong strdup and the good one.
char *wrong_strdup(char *str) {
char *dest;
dest = str;
return (dest);
}
I have a function to dynamically allocate and read a .txt file in C. However according to my assignment instructions the reading of the file should use strdup and not malloc to handle the dynamic memory allocation. I have tried tinkering with the…

I have a function which I pass a character pointer to, like:
funtion_name (char* string){

}
I want to copy the string to a temporary string variable, then copy that into a struct. This is what I have done thus far:

I have a struct containing a bunch of char pointers whose values are used throughout the program's lifetime. Most are overwritten every iteration.
Should these values be freed at any point besides program exit? Should the value in the char pointer…
I have a loop which tries to read data from a qml list object, here is my loop

argvarry[2] = "-a_nodata";
argvarry[3] = "'0 0 0'";
