When using VC6.0 to compile. C file, if you define variables in any place in the program, the above error will occur;
Reason: Generally in ANSI C or C++, it is allowed to define variables at any time in executable code, but in K& It’s not allowed in R and C, and that’s why we have this error. VC6.0, VS2008 are used K& R C to implement the C language, so the compilation process will report errors.
In pure C, variable declarations for a block of code are usually at the front end.
Solution: 1. Put all variable declarations at the beginning.
2. Save the file as. CPP file.
