String to Integer array

Hey I needed some help. How do I convert the string into an integer array in C++ ? I'm taking the string from command line . Edit : After conversion I'm facing problem with the array storage. I've used a for(i=0;str.length();i++) to display the integer array since arr where the array is stored won't have length / size function.

atoi() convert a char array to int int x=0; this is how to convert it manually string str="543; for(int i=0;i<str.length();i++) { x*=10; x+=str[i]-'0'; }
