Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num<0){
        printf("- ");
        num = (~num )+1;
    }   
    char dig[10] = {'0'}; int i=0;
    while(num)
    {
        dig[i++] = '0' + (num%10);
        num/=10;
    }
    i=0;
    for(int x=9;x>=0;x--)
    {
        if(dig[x]>='1' && dig[x]<='9') i=1;
        if(i==1)    printf("%c ",dig[x]);
    }
}

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