Convert Integer to String

Code

#include <stdio.h>

char digits[10] ={'0','1','2','3','4','5','6','7','8','9'};
void print_integer_as_string(int num) {
    // Your logic here
    int MAXTEN = 1000000000;
    int digit;
    if (num == 0) {
        printf("0");
        return;
    }

    if (num < 0) {
        printf("%c ", '-');
        num= -num ;
    }

    while ((int) ((num/MAXTEN) == 0)) {
        MAXTEN = MAXTEN / 10;
    }
    while (MAXTEN > 0) {
        digit= (int) (num/MAXTEN);
        printf("%c ", digits[digit]);
        num = num - digit * MAXTEN;
        MAXTEN = MAXTEN /10;
    }

}

int main() {
    int num;
    scanf("%d", &num);
    print_integer_as_string(num);
    return 0;
}

Solving Approach

Find the leading one dividing the number by the largest power of ten in an int.
