Implement a Simple Shell Command Parser

Code

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

void parse_shell_input(char *line) {
    char buffer[100];
    int i=0;
    int buff_i = 0;

    while (line[i] != '\0') {
        if (line[i] != ' ') {
            buffer[buff_i++] = line[i];
        } else {
            for (int j=0; j < buff_i; j++) {
                putchar(buffer[j]);
                if (j==buff_i-1) printf("\n");
            }
            buff_i = 0;
        }
        i++;
    }

    for (int j=0; j < buff_i; j++) {
        putchar(buffer[j]);
    }
}

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

    parse_shell_input(line);
    return 0;
}
