Answer:
symbolic constants are constants represented by symbols....
constants are values that does not change through out the program execution.
e.g
#include<stdio.h>
#include<conio.h>
#define NUM 15
void main()
{
int a=NUM;
printf("The constant is %d",a);
getch();
}
here #define is a preprocessor. its job is to replace all the entries named NUM as 15. So that the compiler works with the constant 15...
