To enter student id and grades, when the input negative stop input, after and failed in the population, the total number of statistics and failed the student number and fraction of printed,
But the final result of an infinite loop the exam scores, why,

LIST the function of the cycle: the for (I=1; I & lt;=n - 1; N++)N++==& gt; i++
CodePudding user response:
For (I=1; I & lt;=n - 1; N the words of the n + + + +), I will always be a 1, die out in the loop,CodePudding user response:
Because the upstairs has said;for (I=1; Score] [I - 1 & gt;=0; I++)
Change
for (I=1; I & lt; N & amp; & Score [I] & gt;=0; I++)
To prevent cross -
