getline line by line and then store entire lines in an array in C [closed]

Answer 1

This does not make an array of strings:

char **array;
array = malloc(bufsize * sizeof(char));

There are plenty of resources that describe how to do this. eg. How to create a dynamic array of strings. Essentially, you need to allocate space for the array, then allocate space for each the strings, a standard way might be:

char **arrayOfStrings;
unsigned int numberOfElements = 20, sizeOfEachString = 100;
arrayOfStrings = malloc(numberOfElements * sizeof(char*));
for (int i = 0; i < numberOfElements ; i++)
    arrayOfStrings[i] = malloc(sizeOfEachString  * sizeof(char));

As a further note, for your whileloop:

while (getline(&line, &bufsize, fp)) {

Is sufficient. Getline will return 0 once you have finished your file. Read this.
