Implement a Simple Shell Command Parser

Code

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

void parse_shell_input(char *line) {
    int i=0;
    int token=0;
    while(line[i] != '\0' && line[i] != '\n'){
        if(isspace(line[i])){
            if(token){
                putchar('\n');
                token=0;
            }
        }
        else{
            putchar(line[i]);
            token=1;
        }
        i++;
    }
    if(token){
        putchar('\n');
    }
}

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

    parse_shell_input(line);
    return 0;
}
