Why fy=qfei2 + ((qianwan - qw3) * f4);//to want to add this line more than 720 charges)
Correct code fy=qfei2 + (f4 (qianwan - qw3) *)) with brackets to run!
I feel so much more added a bracket is not? There are bosses know? [/color]

That line # define qfei2 less a parenthesis

CodePudding user response:

Suggestions are put, put parentheses around the brackets to write your code in parentheses, so it is not easy to leak the brackets,

CodePudding user response:

//using the cost of 720 
# define qfei2 (qfei + qfei1 + f3 * (qw3 - qw2)) 

Less a right parenthesis ~
