    Arithmetic with a string.

    I have a string "I10014" stored as a char, I need to do arithmetic on each of the numbers individually i.e. 1 * 5, so that I have a result for each sum and then add them all up to have a total. But I want to do it in a function, so will need to pass the string to it.
    Please help.

    You can change a character to the number equivalent by subtracting '0'.
    #include <stdio.h>
    add(char *nums){
        int sum=0;
        if (*nums=='A'){
            while (*++nums!='\0')
            printf("The total is %d\n", sum);
        char b[]="A10014";
    Real respect comes from those that have the knowledge to understand what you've done and the experience to appreciate it. It's the Crack Cocaine of programming.
