C++ ->Trying to read a line of text word by word. How to make a pointer equivalent of the current 2 dimensional array used to store the input -
wrote program read user input, word word
#include<iostream> #include<cstring> int main() { using namespace std; int i=0; char input[50][50]; cout<<"enter input: "; cin>>input[i]; while(strcmp("q",input[i])) { i++; cin>>input[i]; } cout<<endl; for(int j=0;j<i;j++) cout<<input[j]<<" "; return 0; }
currently using two-dimensional character array store input. i'm not pointers since read those.
is there pointer equivalent of char input[50][50]
? know range of [50] bad idea. using pointers should solve right?
i tried doing this-> char* input= new char[50]
, guess wrong way? char* input= new char[50]
create pointer array of strings or pointer array of characters?
please keep simple. started arrays.
char* input= new input[50];
wrong;
char * input = new char[50];
correct.
its creates dynamic 1d array of characters. not array of pointers. if want create 2d array of characters
here syntax
char * arr = new char*[rows]; //creates 1d array of character pointers for(int i=0;i<rows;i++) arr[i]=new char[columns]; //creates array every row, make 2d array
you can assume 2d character array 1d string array, because string character array. more suggest use strings can manipulate string.
