Process

This was a pretty simple challenge. Completing the code, I’ve added a for loop to print each character at a time, scanning for any blank spaces and “replacing” that with a newline escape character \n.

int main() {

    char *s;
    s = malloc(1024 * sizeof(char));
    scanf("%[^\n]", s);
    s = realloc(s, strlen(s) + 1);
    //Write your logic to print the tokens of the sentence here.
    for (int i = 0;i <strlen(s); i++){
        //if(s[i] != ' '){
        //    printf("%c", s[i]);
        //}
        //else{
        //    printf("\n");
        //}
        (s[i] != ' ') ? printf("%c", s[i]) : printf("\n");
    }
    return 0;

Afterthoughts

Looping through each character in the string, a check is done to check for blankspaces and replacing them with a newline character.

I did it using an ordinary for loop but translated that same loop to a ternery operator for elegance. I really like the use of ternery operators in C.

This challenge earned me 20 points!
