How to compare string in arrays???

Answer 1

So you will have to go through each student that has been created so far and compare the currently entered id to the existing id's. You should do this in your id_check function. And since you are passing the loop counter to your function, you can use that in your new loop when you check the accounts that have already been created. Then just return idch=true if any are equal.

for (int x = 0; x < id; ++x) {
if (acc[x].student_num == acc[id].student_num)
return idch=true;
}

Answer 2

So what exactly is happening now that isn't working. When you enter the same name? When you enter the same id? It would help to know what the issue is so I don't have to look at all of this code

Answer 3

I did notice this in name_check:
while (name_check(nch));

You don't want to call name check in the loop and then call it again in the condition. Just call it once in the loop and set it to a bool (since it returns one).

bool a = name_check(c);
} while (a);
