A type-insensitive macro is a macro that performs the same basic operation on different data types. This task can be accomplished by using the concatenation operator to create a call to a type-sensitive function based on the parameter passed to the macro.

A type-insensitive macro is a macro that performs the same basic operation on different data types. This task can be accomplished by using the concatenation operator to create a call to a type-sensitive function based on the parameter passed to the macro. The following program provides an example: #include #define SORT(data_type) sort_ ## data_type void sort_int(int** i); void sort_long(long** l); void sort_float(float** f); void sort_string(char** s); void main(void); void main(void) { int** ip; long** lp; float** fp; char** cp; ... sort(int)(ip); sort(long)(lp); sort(float)(fp); sort(char)(cp); ... } This program contains four functions to sort four different data types: int, long, float, and string (notice that only the function prototypes are included for brevity). A macro named SORT was created to take the data type passed to the macro and combine it with the sort_ string to form a valid function call that is appropriate for the data type being sorted. Thus, the string sort(int)(ip); translates into sort_int(ip); after being run through the preprocessor. read less

By using concatenation operator we can create a type-insensitive macro. For Example: #define ADD(data_type) add_ ## data_type void add_int(int i, int j) { int h = i+j; printf("%d",h); } void add_float(float k, float l) { float m = k+l; printf("%f",m); } void main(void) { int...
