how many numbers are there?

#include <stdio.h>
#include <string.h>

int main()
{
    int T;
    scanf("%d", &T);
    getchar();

    char str[1000000];
    int i, len, count, flag; //flag = 1 >> paichi

    while(T--){
        gets(str);
        len = strlen(str);
        count = 0;

        for(i = 0; i < len; i++){
            if(str[i] != ' '){
                flag = 1;
            }
            else{
                if(flag == 1){
                    count++;
                }
                flag = 0;
            }
        }
        printf("%d\n", count + 1);
    }

    return 0;
}
