Implement a Simple Shell Command Parser

Code

#include <stdio.h>
#include <ctype.h>

void parse_shell_input(char *line) {
    int i = 0,flag = 0;
    while (line[i] != 0){//add newline also
        if(line[i] == ' '){
            if(flag == 0){
                printf("\n");
            }
            flag = 1;
            
        }
        else{
            printf("%c",line[i]);
            flag = 0;
        }
        i++;
    }
    //end with new line
}

int main() {
    char line[101];
    fgets(line, sizeof(line), stdin);

    parse_shell_input(line);
    return 0;
}
