Practice variables, arithmetic, and string concatenation by printing a tiny one-item receipt.
You start with:
item := "Coffee Mug"
price := 12
quantity := 3
Build:
Coffee Mug x3 Total: $36
Rules:
- Compute
total := price * quantity. - First line:
"<item> x<quantity>"(e.g."Coffee Mug x3"). - Second line:
"Total: $<total>". - Join the two lines with a newline
"\n"into one stringresult, then print it withfmt.Println(result).
Wrap each integer with
strconv.Itoa(...) before concatenating it with +.
line1 + "\n" + line2 joins both lines into one string.
item := "Coffee Mug"
price := 12
quantity := 3
total := price * quantity
line1 := item + " x" + strconv.Itoa(quantity)
line2 := "Total: $" + strconv.Itoa(total)
result := line1 + "\n" + line2
fmt.Println(result)
