I am having a problem using intellisense for my custom headers file in for c++ in vscode

Question

I tried compiling my shopping program with IntelliSense in vs code but is not working. Both the program and the header file are in the same folder called Shopping_program but that folder is in another folder called c++ which is where my .vcode folder is.

shopping_program.cpp

#include "shopping.h"
int main(){
    do{
        clear();
        choice();
        calculateTotal();
        receipt();
    } while(again());
    cout << "Thanks for shopping";
   
    
}
