wish help you to fix your issue I tried running following C program and got Segmentation fault, I am not getting where the code is wrong, the output is saying Program finished with exit code 139.
code :
   printf("\n S==>>> %s",*a[0]);
 printf("\n S==>>> %c",*a[0]);  // *a[0] is of type char
 printf("\n S==>>> %s",a[0]); // a[0] is of type char *

My program is giving me a segmentation fault (c++)

around this issue You're incrementing pointerindex on every pass through the loop, rather than just after you read in the contribution amounts. So by the time you get to reading in 5006, you have pointerindex == 3, which causes a segfault on carray[pointerindex].
Move ++pointerindex into the else statement.

I created this program, but its giving output "segmentation error (core dumped)" , what do I do?

help you fix your problem I created this program for assignment. Compiler complies it but when I run to check the output, it gives the following error: , The error lies in your constructor of List:
code :
List() {
    headnode = new Node();
    currentnode->setnext(NULL); // <--- error is here!
    currentnode = NULL;
    lastcurrentnode = NULL;
    size = 0;

Why is this program giving 'Segmentation Fault'?

this one helps. I've been trying to implement the concept of merging two dynamic sequences, which are already sorted when provided as input. Why is it producing 'Segmentation Fault' every time? The program first takes the size of two sequences and dynamically allocates memory for them. After the elements are taken as input, a function named merge() is called to implement the concept. It takes two pointers to the sequence and returns another sequence of twice the size of the entered sequences having merged sequences. Here, one should note that input sequences are already sorted.
code :
while( count < 2 * size ){
    while( *(obj1 + i) <= *(obj2 + j) ){
        *(temp + count) = *(obj1 + i);
*(obj1 + i) where i>=number of elements in obj1
while( i < size && j < size)
    if ( *(obj1 + i) <= *(obj2 + j) )
        *(temp + count) = *(obj1 + i);
        *(temp + count) = *(obj2 + j);
while (i < size)
    *(temp + count) = *(obj1 + i);
while (j < size)
    *(temp + count) = *(obj2 + j);

may help you . Because dereferencing a null pointer (head IS null) is undefined behavior whose consequence can be a segmentation fault:
code :
if(head == nullptr) //if the list is empty
    head -> next = new SinglyLinkedListNode(data);

Why is my recursive program giving me a segmentation fault?

I think the issue was by ths following , Because you are not passing arguments to scanf properly, as reported by the compiler:
