c++ - Correcting a segmentation fault -

#include <iostream> #include <stdio.h> #include <math.h> #include <stdlib.h> using namespace std;  int main(){     int i=0,n,h,k;     k = (int)pow(10,5);     int c[k];     scanf("%d%d",&n,&h);      if((n>=1 && n<=(int)pow(10,5)) && (h>=1 && h<=(int)pow(10,8))){        int arr[n];        do{           scanf("%d",&arr[i]);           if(arr[i] > h){             cout<<"error !";             exit(1);           }           i++;       }while(i!=(n-1));        i=0;        do{                    /*the fault occurs somewhere here, probably*/           scanf("%d",&c[i]);           i++;       }while(c[i]!=0);        if(i>(int)pow(10,5)){           cerr<<"error !";           exit(0);       }      }     return 0; } 

i'm trying accept few numbers console on different lines using scanf() (with constraints on upper , lower limits of numbers) - problem i'm getting segmentation fault somewhere around i've put comment - can't seem figure out fault occurs - point out mistake i've made ?

i think problem here

do{                        scanf("%d",&c[i]);      i++;  }while(c[i]!=0); 

consider current value of i 0 , entering value @ c[0] after increamenting value of i. i become 1 , checking c[1] != 0 problem

use

i=-1;  do{           i++;                   scanf("%d",&c[i]);   }while(c[i]!=0);
