Program error, change wrong, can you help me take a look at how to change-CodePudding

For subsequent request is to analyze the status code access statistics, calculating the ratio of all access status code, so I just defines a lot of array, may be an error in the group in walking down there? Compile a hard, just checked data array subscript the problem might be illegal, who teach me

How to understand this?
The line array name, I & lt; What's the line,
Line [I], the status of this as a subscript and commas, then the status is array name,

Such code is not in conformity with the rules of grammar, naturally prompt compiler error,

I put the correct line to the line after the [I], the program's warning, but behind the status don't know how to change

How to change, want to see what you want to achieve, what is the status for, besides the above didn't assign the status
