Code:#include <stdio.h> int main() { int marks[50],i,n,sum=0; float avg; printf("ENTER THE NUMBER OF STDENTS(should not exceed 50): \n"); scanf("%d",&n); for(i=0;i<=n;i++) { printf("STUDENT NUMBER %d SCORED:\n",i+1); scanf("%d",marks[i]); sum+=marks[i]; } avg=sum/n; printf("THE AVERAGE MARKS OF STUDENTS ARE %f",avg); return 0; }
plzz tell me whats wrong with this program... every time i try 2 run this errors occur...
Could you please also copy'n'paste the error? I still haven't met any mind reader here.Originally Posted by suvojit biswas
And please use normal English (no "plzz" and "2" instead of "to").
If n == 50 (or bigger) then "i" will get up to 50 too and marks[i] == marks[50] is undefined behavior.Code:for(i=0;i<=n;i++) { printf("STUDENT NUMBER %d SCORED:\n",i+1); scanf("%d",marks[i]);
I.e. your "<=" should be "<".
Edit: And scanf("%d") expects a pointer to int but marks[i] is an int.
"sum" is an int, "n" is an int, thus the result of "sum / n" will be an int too and then it will be cast to a float.Code:avg=sum/n;
