Smiley face when assigning improper value type to struct property!!

Answer 1

Your problem is here:

lineData.name = 1;
lineData.grade = 2;

I should note that the symbols you're getting are ASCII 1 (ie, exactly what you're setting lineData.name to).

while( getline(myFile, line) )

You need to take the line and parse it, inserting a proper string into lineData.name, and inserting an integer into lineData.grade.

Answer 2

The smiling face is the character with ASCII value 1. Not sure why, but apparently your compiler decided to treat it as a char, so you get the smiley.

Answer 3

The string is being assigned a character value (1), which happens to be a smiley face in the ASCII character set.

Answer 4

I WANT TO KNOW WHY IT IS GIVING ME SMILEY FACES INSTEAD OF ERRORS

Because the datatype is string, and the char 0x01 prints a smile-face. You possibly what to assign the value 0x31 instead, which is the character 1, in ASCII.

Answer 5

Like others have said name is of type string, so it would be best to assign a string to it:

lineData.name = "1";

the inverted commas will let the compiler know that this value is a string, and you will stop getting smiley faces.

that said...

Coolest. Bug. Ever.
