Implement a Simple Shell Command Parser

Code

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

void parse_shell_input(char *line) {
    bool newWord = false;
    for(int i=0;line[i]!='\0';i++){
        if(line[i]==' ') newWord = true;
        if((line[i]>='a' && line[i]<='z')||(line[i]>='A' && line[i]<='Z')||(line[i]>='0' && line[i]<='9')){
            if(newWord) newWord=false,printf("\n");
            printf("%c",line[i]);
        }
    }
}

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

    parse_shell_input(line);
    return 0;
}
