Explanation of Solution
Analysis of Amazon and Walmart using the competitive forces and value chain:
The below is the analysis that is made based on the competitive forces and value chain:
Walmart:
- Walmart is considered to be one of the traditional marketers that are laid with stronger supplier relationship.
- The customer relationship is being developed and strengthened by providing low price offerings on various products, the price that is offered will be in the way that it may not be offered anywhere else.
- It completely relies on the strategy low-cost leadership to retain its customers.
- The supply replenishment chain is made continuous with its efficient customer response system.
- The customer response system is strengthen with the use of information technology‘s value chain.
- The value chain is mainly concentrated with the activities such as operations, sales, inbound logistics, marketing and the service that undergoes.
Amazon:
- It is considered as new market entry where the customers are drawn based on the products and service that are provided to it in a different form such that it attracts its customers based on their requirements...

This problem tests your understanding of the program stack. Here are some notes to
help you work the problem:
⚫ strcpy(char *dst, char *src) copies the string at address src (including
the terminating '\0' character) to address dst. It does not check the size of
the destination buffer.
• You will need to know the hex values of the following characters:

Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function.
