The trouble here is that I can't declare variables inside a function after the function already has some statements in it. Declaring at the start works fine, but after something, it gives a parse error. For example: int main() { int b; b = sisesta(); float st[b]; return 0; } I'd like to declare an array `st` with its size being returned by another function, but it won't let me do it! Says "Parse error before float". This is in C by the way, but I guess its identical to what it would be in other languages with the same syntax. Any help appreciated.
