my task is to draw a random number as a ticket in a lottery. Then I need to guess what number is it. This operation of guessing needs to be done 100 times. I don't know if my program works good because every time I print the chances on the screen it gives me the proper answer in each step. I have steps variable globally declared, so probably that's why it is always the same. But what about chance?
#include<stdio.h>
#include<time.h>
int fchance(int min, int max, int ticket);
int steps = 0;
int main(void) {
int ticket, chance;
int i;
int stepsInTry = 0;
int stepsAverage;
srand(time(NULL));
// rand() % (max - min) + min;
for (i = 0; i < 100; i++) {
ticket = rand() % 100 + 1;
printf("Your ticket: %d ", ticket);
steps = 1;
chance = rand() % 100 + 1;
printf("\nChance: %d", chance);
while (ticket != chance) {
if (chance < ticket) {
chance = ftraf(chance, 100, ticket);
printf("\nChance: %d, step: %d", chance, steps);
}
if (chance > ticket) {
chance = ftraf(1, chance, ticket);
printf("\nChance: %d, step: %d", chance, steps);
}
}
printf("\nOperation nr: %d - number of steps: %d \n", i+1, steps);
stepsInTry += steps;
system("PAUSE");
}
stepsAverage = stepsInTry / 100;
printf("\n\nAverage of steps: %d ", stepsAverage);
system("PAUSE");
return 0;
}
int fchance(int min, int max, int ticket) {
steps++;
int chance;
chance = rand() % (max - min) + min;
if (chance < ticket) {
chance = fchance(chance, 100, ticket);
printf("\nChance: %d, step: %d", chance, steps);
}
if (chance > ticket) {
chance = fchance(1, chance, ticket);
printf("\nChance: %d, step: %d", chance, steps);
}
return chance;
}
The example of output:
Your ticket: 65
Chance: 38
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Chance: 65, step: 11
Operation nr: - numbers of steps: 11
@EDIT
Sorry for the mess in the code. Changed variable names from my native language to english.
