Annotation conversion (c to c ++)

Annotation conversion (c to c ++)

// The process in input. c is as follows:

The results in output. c should be as follows:

 

 

// Int I = 0;


// Int y = 0;
Int j = 0;
// Int x = 0;/* 12345678


//
// Int h = 0;
// Int g = 0;
// Int j = 0;
//
Int q = 0;
//
//
