Implement a Simple Shell Command Parser

Code

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

void parse_shell_input(char *line) {
    int flag = 0; 
    int i = 0; 
    while (*line != '\0'){ 
        if(*line != ' '){ 
            printf("%c", *line); 
            flag = 0; 
        } else { 
            if (flag == 0){ 
                printf("\n"); 
                flag = 1; 
            }
        }
        line++; 
    }
}

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

    parse_shell_input(line);
    return 0;
}
