To include the value of a variable in a string you can use the function paste() or paste0():

FYI, your reproducible example is a grouped dataframe, that's why I passed it to ungroup first. If it weren't a grouped dataframe then you do not need that pipe.

Arrays start at 0, not 1. When using ArraySize to define counting of arrays, you should always minus 1 to account for starting at 0.

Your plugin is creating separate elements for images and description which are dynamic so you cannot change that also currently there will be two buttons which has same id one which is created statically and another created by plugin that's why when you do document.getElementById(clicked_id).innerHTML .. the button which is static is getting change and you can see changes in slider when you re-open it .

Instead you can use data-attributes so whenever your button is clicked change the button which is static and which is created dynamically so that you can see changes without closing and re-opening your slider.

Demo Code :

You have a problem with the second useEffect, the first time you update your state userRegistrationError, the component re-rendered and re-executed the useeffect because the dependency userRegistrationError has changed and the process gets repeated again because the state gets updated every render.

Rewrite to

booklist1[i] = *(booklist1+i),thenbooklist2[i][j] = *(*(booklist2+i)+j), if j=0, then *(*(booklist2+i)+j) = *(*(booklist2+i)+0) = *(booklist2[i]) = *booklist2[i]

booklist2[0] points to first row, booklist2[1] points to seconds row, and so,... on.

You are defining an array of book pointers (2D array) : book* booklist [MAXBOOKS]
But list is an array of book (1-D array). After execution this statement, lib CurrentLibrary = {3,{list}}; list array will be stored into booklist[0] row. But all other pointers of booklist[1], booklist[2],..... booklist[9] are not pointing to any element. But, you are accessing booklist[1], booklist[2], and booklist[3] in the printLibrary function. This is the reason for Segmentation fault.

For more insight (for 2-D array), please print the following lines:

printf("Title %s\n", library.booklist[0][0].title); prints--> Title The trial printf("Title %s\n", library.booklist[0][1].title); prints--> Title The lurking fear
printf("Title %s\n", library.booklist[0][2].title);prints-->Title Dora's storytime collection

But trying to access, library.booklist[1][0].title will throw segmentation fault, since second row pointer is not pointing to any element.

I think this should work:
