Implement a Simple Shell Command Parser

Code

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

void parse_shell_input(char *line) {
    // Your logic here
    int a,idx=0;
    while(line[idx]!='\0'){
    
       if(line[idx]==' '){
           if(a==0){ 
            printf("\n");
            a=1;}}
        else {printf("%c",line[idx]);a=0;}
        idx++;
    }
}

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

    parse_shell_input(line);
    return 0;
}
