When I run the program by itself, it works but it will give my the error message only when I print two or more characters. If I enter a,b,c it sees them as too low.
And when I add this to my full program as a function it gives me this error [Error] 'EOF' undeclared (first use in this function)
[Note] each undeclared identifier is reported only once for each function it appears in.
Code:
#include <stdlib.h>#include <string.h>
#include <time.h>
#include <ctype.h>
void instructions() {
printf("\nHere are the instructions:\n");
printf("1. Pick a number between 1 and 100 and the computer will tell you if it's too high or too low.\n");
printf("2. Pick a number between 1 and 100 and the computer will tell you \n if it's too high or too low and validate your input.\n");
}
void subMenu() {
printf("Additional instructions:In game one you must guess my secret number between 1 and 100. I will tell you when you're correct");
printf("In game two the computer will select a random number from 1 to 100 and you have to guess it");
}
void user_guess() {
int secretnum=5, guess, tries = 0;
printf("Guess My Secret Number Game\n\n");
// Takes user input and compares it to the secret number stored in the secretnum variable
do
{
printf("Guess My Secret Number. It's between 1 and 100 : ");
scanf("%d", &guess);
tries++;
if (guess > secretnum)
{
printf("Too high!\n\n");
}
else if (guess < secretnum)
{
printf("Too low!\n\n");
}
else if (guess == secretnum)
{
printf("That is correct!");
}
}while (guess != secretnum);
return 0;
}
void computer_guess() {
int num,flush, guess, tries = 0;
srand(time(0)); /* seed random number generator */
num = rand() % 100 + 1; /* random number between 1 and 100 */
printf("Guess The Computer's Serect Number\n\n");
// Takes user input and compares it to the random number chosen
do

printf("Enter a guess between 1 and 100 : ");
scanf("%d", &guess);
while( (flush=getchar()) != EOF && flush != '\n');

}

}

}
