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
