What is accomplished by the call to sprintf in the code fragment below?

``` char ans[20]; int num = 40; sprintf(ans, "%d to %d", num, num + 10); ``` a. Nothing, the function name is misspelled. b. It returns as its value the string "40 to 50". c. It displays first the value of ans and then the string "40 to 50" (without the quote marks). d. It aborts because the value of ans is garbage. e. None of the above.

Modify example program 1 to average the values: 33, 47 and 29 instead of the given data.

Replace LET numl =10 Replace LET num2 =15 Replace LET num3 = 20 with LET numl = 33 with LET num2 = 47 with LET num3 = 29
