Hi ,
This code has errors.
You are using s[i].total=0;
This won't work coz
1. s is not an array
2. you have not set any values to the int variable i
You have to create an array of structure like this
struct student arr[10];
then you have to iterate loop to set values
Now scanf("%s",&s[i].name); is also wrong as format '%s' expects argument of type 'char *', but here it has type 'char (*)[20]'
change it to
scanf("%s",s[i].name);
Please make these changes and let me know if any issues
I have edited the code and you can find the fully edited and working code here
