Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char str[16];
    
    int i=0,is_negative=0;
     if (num == 0) {
        printf("0");
        return;
    }
     if (num < 0) {
        is_negative = 1;
       num=-num;
    }
        while(num>0){
     int dig=num%10;
     str[i]=dig+'0';
     num=num/10;i++;
    }
     if(is_negative){
        str[i]='-';i++;
    }
    for(int j=i-1;j>=0;j--){
        printf("%c ",str[j]);
    }

}

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