One, the topic requirement (arithmetic 3)

1, the student writes the procedure must be able to determine the user's input answer is correct, for example the program output: 20–5 =? user Input 15, then the program will feedback correctly, and then continue to the question. Until the end of the 30-word problem, the program finally told the user to do a few questions.

2, the program must be able to handle four kinds of calculation of the mixed formula;

N20–5 * 2 =?   The correct answer is 10.n20–5 * 2 + 9/3 =? The correct answer is 133, note: Continuous subtraction and division, should abide by the provisions of the left combination. Continuous division to parentheses, otherwise it will cause ambiguity

Second, the design idea

Third, the source program code

Iv. Results of operation

V. Programming Summary and Analysis

Vi. Log of time logs
