Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char arr[10]={0};
    int flag=(num<0)?-1:1;
    int i=0;
    if (num==0)    printf("%c",'0');
    while(num){
        arr[i++]=(flag*num)%10 + '0';
        num/=10;
    }
    if (flag==-1) arr[i++]='-';
    for (int j=i-1;j>=0;j--)
        printf("%c ",arr[j]);
}

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