It seems like you're on the right track, but there are a few details you need to work on. First, srand is the function to seed the random number generator, you only use it once. The rand function returns a value in the range 0 to RAND_MAX, so you need to do something to get your generated random into the range you need, 1 - 100. See the random function I defined for this purpose. I also recommend against using scanf. It's much easier to protect yourself against bad input causing your program to misbehave if you use fgets and sscanf. See below for how I would do this. If you see something you're unfamiliar with, look it up, it's a good way to learn. #include #include #include #include #define MAX_LINE_LEN 256 #define MIN_VAL 1 #define MAX_VAL 100 int random(double rangeMin, double rangeMax); int main(int argc, char *argv[]) {    time_t t;    int count = 0, answer, guess = -1;    char line[MAX_LINE_LEN];    srand((unsigned)time(&t));    answer = random(MIN_VAL,MAX_VAL);    printf("\nGuess the number between %d and %d\n",           MIN_VAL,MAX_VAL);    while (guess != answer) {       printf("> ");       fgets(line,MAX_LINE_LEN,stdin);       if (sscanf(line,"%d",&guess) == 1) {          if (guess < answer) {             printf("too low\n");          } else if (guess > answer) {             printf("too high\n");          } else {             printf("correct!\n");          }       } else {          printf("invalid entry, try again.\n");       }       ++count;    } /* end while number not guessed */    printf("\nnumber of guesses = %d\n",count);    return 0; } int random(double rangeMin, double rangeMax) {    double maxN;    assert(rangeMin <= rangeMax);    maxN = rangeMax - rangeMin;    return (int)(((rand() / (double)RAND_MAX) * maxN) + rangeMin); }

Answer 3

u should practice this programms by urself then only u can able to develop ur programming skills, if u have any doubt then u can surely ask but whole assignment u should practice by ur self only....

Answer 4

i cant type all the answers here. no1 will waste their time.

re-ask the question which you feel is difficult for you, and i'll solve it.

Answer 5

Do your own homework!!
