This is a simple list of creation and output, but I'm not out of any compile-time errors, run out quite a few problems
1, 1 is in the input score, enter a decimal number, press enter to output directly, and there is a problem in the output screenshots:
2, 2 is in the case of not enter the decimal point, after the output data by 10,
This is how to return a responsibility, meng directly,
CodePudding user response:
The scanf (); Function is formatted input of meaning, the format is what you write (" % d, % f "), then you should also be as input 4564 32.0 to 4564,32.0 wouldn't be a input decimal output directly;You find every time output data by 10 should be or format, the scanf don't think you input the second number, so I think the second number is zero, you haven't separate formatting output of two Numbers, you enter 123, 123, the program think you input is 123, 0 123, 0 so give you 1230, 1230, the output looks like by 10

Also not ah, add don't add, or useless
CodePudding user response:
The results of your program that I run, you see my input
CodePudding user response:
You have a look at the scanf input format is what, is missing a comma, and is a comma in English;# include
