This code in C works properly when I use code::blocks or any online compilers, however if I try to use this in VSCODE it returns
“expected type-specifier before ‘;’ token on LN 5, Col 18”
“expected type-specifier before ‘)’ token on LN 13, Col 26”
“expected type-specifier before ‘)’ token on LN 20, COL 21”

I am a beginner learner of the C programming language. I just started learning this language, this year at the beginning of July. I am trying to learn the basics of C programming before going to university this September.

while building the project, I am getting this error

Enhance the tic-tac-toe game so 2 people can play. To do this, you need to add an“O” that, like the “X”, is drawn in the square. Then prompt the user for a square identifier, and alternate between drawing “X”s and “O”s at those locations on the board. The first move is for “X”. You need to detect and reject when a user plays a square that is already taken. Stop after the board is full (that is, 9 plays). You do not have to worry about who wins.
The “O” is to be 5 × 5, centered in the middle of the square.
