declares a function, but that does not define it.
declaration describes whether the function consist
arguments or not and also it will return a value or not.
definition must be as per the function declaration that was
declared rearlier.it will for the out put of that function.
ex;
main()
{
int a=1,b=2;
void sum(int , int );//declaration
sum(a,b);
}
void sum(int x, int y)//definition
{
printf("%d",x+y);
}
