Delete Data from a struct

So, Im kinda new to C. I am making a simple I/O Program but facing a problem.
So I have this Struct:

Code:

---

struct stock{ //Struct for storing stock data
            char item_name[100];
            float item_rate;
            int item_quantity;
   
            }stock_[MAX_SIZE];

---

For Example, I Input the following Data:
1.
item_name: shoes
item_rate: 100
item_quantity: 200

2.
item_name: shoes
item_rate: 100
item_quantity: 200

Now I want to delete the second entry of data from struct ie shoes, its rate and its quantity. How do I do that? For now I am using the strcmp to compare input string with that of data saved and replace it with Null string using strcpy. But that doesnt seem feasible solution to me.
Here is my Code:

Code:

---

char item_delete[50];
char new_name_delete[50]={'\0'};
int compare_delete;
retry_search_case_3:
printf("\n\t\tEnter item name to Delete(case sensitive): ");
scanf("%s",item_delete);
for(i=0;i<index_stock;i++)
{
compare_delete=strcmp(stock_[i].item_name,item_delete);
if(compare_delete==0)
{
printf("\n\t\t%s item found. Its Entry Number in Stock is %d\n\t\tDeleted this Item from Stock\n\t\tPrinting Updated Stock...\n\t\t",item_delete, i+1);
 strcpy(stock_[i].item_name,new_name_delete);
 stock_[i].item_rate=0;
stock_[i].item_quantity=0;
system("pause");               
break;
 }
                           
else
{
printf("\n%s item not found! Please try again: ",item_delete);
continue;
}

I know how to delete a simple element from a 1D Array, I tried to implement that here but didnt work. As that algorithm compares two input integers instead of strings and then re-sorts the array

Maybe something like this. I couldn't test it since you didn't give me a full program. I'm assuming "index_stock" is what might better be called stock_size, the current number of active elements in the array.

Code:

---

    printf("Enter item name to delete(case sensitive): ");
    scanf("%s", item_delete);
 
    bool found = false;  // you can include <stdbool.h> for bool, true, false
    for (int i = 0; i < index_stock; i++)
    {
        if (strcmp(stock[i].item_name, item_delete) == 0)
        {
            printf("%s item found. Its Entry Number in Stock is %d\n"
                  "Deleted this Item from Stock\n", item_delete, i+1);
            --index_stock;
            for ( ; i < index_stock; i++)
                stock[i] = stock[i + 1];
            found = true;
            break;
        }
    }
 
    if (!found)
    {
        printf("%s item not found.\n", item_delete);
    }

Thank you John C. It worked!
