Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    int i=0;
    char nstr[10];
    if(num==0){printf("0");return;}
    if(num<0){printf("- ");num*=-1;}
    while(num>0){
        nstr[i++]=((num%10)+'0');
        num/=10;
}
    for(int j=i-1;j>=0;j--){printf("%c",nstr[j]);if (j>0){printf(" ");}}
    
}

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