C Language:

BASIC has print ? myVar that bundles up the variable name & value. Available in C? I'm using a flavor of C for microcontrollers Thanks

有帮助吗?

解决方案

You can define a macro:

#define PR_INT(x) printf(#x"=%d\n",x)
#define PR_CHAR(x) printf(#x"=%c\n",x)
#define PR_STRING(x) printf(#x"=%s\n",x)

and so on

There is no such feature built into the language because the variable name is just a label,which the compiler may not need after the parsing stage (still needs the global variables)
