Modulus is division, if n=0 will cause in addition to the zero error,CodePudding user response:
Debugging when I tried to the commented outShow n is not equal to 0
CodePudding user response:
Int a, [3].A [3]=rand () % strlen (b); Crossing the line,
Other did not check,
CodePudding user response:
Then how to modify? I don't know much about c + + cross-border all heard what haven't seenCodePudding user response:
Int a, [3].//array defines a here, only three elements,A [3]=rand () % strlen (b); Crossing the line,//C/C + + array subscript begins with 0, a [3] is the fourth element,
You only defines the three elements, is assigned to the fourth element, this behavior is called crossing the line, can produce unpredictable behavior,
Change the method is very simple,
Int a, [4].//define the four elements of an array, you can use a [3]
