store a string to an integer array

[Mohammad Sianaki]

Hey I'm a beginner in C++. I want to read a number(8-10 digits) as a string and then copy it into an integer array but I have no idea how to do it.

copy it into an integer array

You mean copy individual digits of the string to the array?

Or do you mean copy the entire number as an integer to a single element of the array?

You'll want to convert from string to int, many ways of doing this. Read this thread - http://www.cplusplus.com/forum/general/13135/

I want to store each digit in an element

Thanks. Well, to convert from a character such as '5' to an integer, this will work:

char ch = '5';
int num = ch - '0';

That is, subtract the character zero from the digit character to get its value as an integer.

To store in an array,

string input = "76543";
int array[30];
for (int i=0; i<input.size(); i++)
    array[i] = input[i] - '0';
