comparing an inputted string to a printed function - c

Question

Below is a code I wrote for a dice game called cho han. To input your guess I've used number to represent the words 'odd' and 'even'. Since then I have tried to write it again, but to actually write odd or even in the scanf section, but can't get it to work. Any help would be appreciated :)
//cho-han
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(void)
{
srand(time(NULL));
int x = (rand() % 6) + 1;
int y = (rand() % 6) + 1;
int result = 0;
int guess = 0;
printf("The values of two dice rolls will be added up. The aim is to guess whether that total number will be odd or even.\n");
printf("To guess odd, enter '1'. To guess even, enter '2'.\n\n");
printf("Please enter your guess for the combined total of the two dice rolls: ");
scanf_s("%d", &guess);
if (guess == 2)
{
printf("\nyour guess is even.\n");
}
if (guess == 1)
{
printf("\nyour guess is odd.\n");
}
if (guess > 2 || guess < 1)
{
printf("\nInvalid guess.\nYou lose!\n");
return (1);
}
printf("\ndice roll 1 = %d\n", x);
printf("dice roll 2 = %d\n", y);
result = x + y;
printf("\ncombined total of both rolls is %d", result);
if (result == 1 || result == 3 || result == 5 || result == 7 || result == 9 || result == 11)
{
printf("\ncombined total of both rolls is odd.\n");
}
else
{
printf("\ncombined total of both rolls is even.\n");
}
if (guess == 1 && result == 1 || guess == 1 && result == 3 || guess == 1 && result == 5 || guess == 1 && result == 7 || guess == 1 && result == 9 || guess == 1 && result == 11)
{
printf("\nYou win!\n");
}
else if (guess == 2 && result == 2 || guess == 2 && result == 4 || guess == 2 && result == 6 || guess == 2 && result == 8 || guess == 2 && result == 10 || guess == 2 && result == 12)
{
printf("\nYou win!\n");
}
else
{
printf("\nYou lose!\n");
}
return 0;
}

You should change scanf_s to scanf
The line if (result == 1 || result == 3 ... could be if (result % 2 == 1) {
You could use strcmp to solve your question
The following code could work:
//cho-han
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>
int main(void)
{
srand(time(NULL));
int x = (rand() % 6) + 1;
int y = (rand() % 6) + 1;
int result = 0;
int guess = 0;
char buf[10];
printf("The values of two dice rolls will be added up. The aim is to guess whether that total number will be odd or even.\n");
printf("To guess odd, enter 'odd'. To guess even, enter 'even'.\n\n");
printf("Please enter your guess for the combined total of the two dice rolls: ");
fgets(buf, sizeof buf, stdin);
if (strcmp(buf, "even\n") == 0) {
guess = 2;
printf("\nyour guess is even.\n");
} else if (strcmp(buf, "odd\n") == 0) {
guess = 1;
printf("\nyour guess is odd.\n");
} else {
printf("\nInvalid guess.\nYou lose!\n");
return 1;
}
printf("\ndice roll 1 = %d\n", x);
printf("dice roll 2 = %d\n", y);
printf("\ncombined total of both rolls is %d", x + y);
result = (x + y) % 2;
if (result == 1)
printf("\ncombined total of both rolls is odd.\n");
else
printf("\ncombined total of both rolls is even.\n");
if (guess == result)
printf("\nYou win!\n");
else
printf("\nYou lose!\n");
return 0;
}

You need to change your guess to char type and scanf to capture string.
char guess[256];
scanf("%s", guess);
And then the best way would be to call toupper() and compare with your text using strcmp().
