how to convert character to integer in C or C++

Question

How can I assign variable x of type int the value 3 from the char variable ch = '3'??.

    char ch = '3';
    int x;
    // assign 3 to x using ch.

`int x = ch - '0';` should work fine. – πάντα ῥεῖ Oct 09 '21 at 17:58 — πάντα ῥεῖ, Oct 09 '21 at 17:58
