In this example, we will declare an integer variable and 1) an integer pointer, 2) a pointer to pointer that will store the address the address of first pointer (integer pointer).#include <iostream> using namespace std; int main() { int a; //normal integer variable int *ptr; //...
(m);// using throw block to transfer error to catch block;} err=0;// if all the conditions are false then value of error variable// is 0}catch(inte) { cout<<"Invalid Marks"<<endl;// Showing error;err=1;// Changing value of variable to retke input;} }while(err);// it ...
