Hi,
I'm trying to write a simple program to learn and use array and pointer. It copies values from a vector to an array and prints the value of the array. Here is the portion of the code that causes problem:
Here is the output:Code:int *pArr = new int[vect.size()] ; int *pArrBegin = pArr ; for ( vector<int>::iterator itr = vect.begin() ; itr != vect.end() ; itr++ ) { int *pItr = pArr; *pItr = * itr ; pItr++ ; } cout << "Print Array: " << endl ; for ( int *pArrItr = pArrBegin , *pArrEnd = pArr + vect.size(); pArrItr != pArrEnd; pArrItr++ ){ cout << * pArrItr << " " ; }
I just don't understand why when I increment pltr, pArr and pArrBegin is also incremented.Code:./copyVectorToArray 1 2 3 4 Print vec: 1 2 3 4 Print Array: 4 0 0 0
