Segfault Pset6 Check()

Question

I receive a segfault at this line of code

    if (pathCheck -> children[charVal] == NULL) {
    
        return false;
    }

pseudocode buildup:

initialise pathCheck to NULL 

while character is not \0

initialise character as character of input word

initialise value of character (c - 'a')

change to lower

then check if NULL (as above) 

Any ideas?

There was no allocated memory for the node pointer. I fixed this by assigning memory for the node using:

malloc root = malloc(sizeof(node));
node* pathCheck = root;
