Thank you very much for help...


I,m thai, I know english a little bit .

I'm sorry, if some word I type you don't know.

[noobiept]

you want to turn the while into a for loop?

btw, use fgets() instead of gets and declare the main function as int main(void).

[Steve Cao]

The variable "nam" must be a string array when you call gets() to initialize it.BTW, the variable "no" hasn't been initialized.

BTW, the variable "no" hasn't been initialized.

Yes it has:

printf("Enter number of student : ");
scanf("%d",&no);

... better indentation of the original post's code is recommended.

I can run this question by...

change int x; to float x;

and

printf("\nStudent No.%d",x );

to

printf("\nStudent No.%0.0f",x );



thanks everyone for Advice.
