strcmp() function only works on first iteration C

Question

I need to make a program that outputs all lines that contain a matching string "target" and sum up the number of matches along with the total cost,

The problem is that the for loop stops at the first iteration regardless of there being a match

I have tried using strstr() instead of strcmp() and it works, but since this is a school assignment, i cant use strstr()

#include<stdio.h>
#include<string.h>

struct data{
    
    char product[100];
    char name[100];
    int price;

};

int main(){

    FILE *f;
    
    f = fopen("Customers.txt", "r");
    int x;
    
    
    scanf("%d",&x);
    
    struct data arr[x];
    
    for(int i=0;i<x;i++){
        fscanf(f,"%[^,], %[^,], %d",arr[i].product,arr[i].name,&arr[i].price);
    }
    
    char target[100];
    int res;
    int count=0;
    int total=0;
    
    scanf("%s",target); 

    for(int j=0;j<x;j++){
        
        res=strcmp(arr[j].product,target);
        
        if(res==0){
            printf("%s, %s, %d",arr[j].product,arr[j].name,arr[j].price);
            count++;
            total = total + arr[j].price;
        }
        else{
            continue;
        }
    }
    printf("\nTotal Buyers: %d\n",count);
    printf("Total Amount: %d\n",total);

}

File:

Gem, Alice, 2000
Gold, Bob, 3000
Gem, Cooper, 2000

Input: 3 (No. of lines in the file) Gem (target)

Expectd output:

Alice 2000
Cooper 2000
