Function Declaration means telling the compiler what are the types of arguments that are passed toa function , what type of data type it will return. It is ended with a semicolon (;).

Eg :
int add(int , int);
int add(int a, int b);

Definition of a function is the original logic that is written.What to do with the parameters passed and what has to be returned.

Eg :
int add(int a, int b)
{
     int c;
    c = a + b;
    return c;
}

Note: Here there is no semicolon for definition.
