Thread: how do i make this loop???

Code:

main()
{
int x;
int r;
unsigned NULL;
printf("I have a number between 1 and 10.\n");
printf("Can you guess my number?\n");
printf("Please type your first guess.\n");
scanf("%d", &x);
srand( time(NULL) );
r = 1 + ( rand() % 10 );
if ( r == x ){
	printf("Excellent! You guessed the number!\n");
	printf("Would you like to play again (y or n)?\n");
}
else
while ( r != x ){
	if ( r > x ){
	printf("Too low. Try Again.\n");
}
	if ( r < x ){
	printf("Too high. Try Again. \n");
}
		printf("Please type your second guess.\n");
		scanf("%d", &x);
}
	printf("Excellent! You guessed the number!\n");
	printf("Would you like to play again (y or n)?\n");
}

trying to design a game that allows user to guess a computer generated number but once the user is correct i don't know how to loop back to play again. Any suggestions on how to create this loop? thanks

i know where the loop needs to be my question was more along the lines of how do i create the loop while (?) and how do i use the user's respons (y or n) to return a true or false for the loop?

how should i define NULL in srand( time(NULL) );? i thought unsigned was the correct way?

Also i just went through the tutorial on loops and it didn't tell me anything about changing a user's response "y" or "n" into a value that can be used in repeating a loop. if you could help me with this i was appreciate it.

yeah i am unsure how to recieve their response, is it possible with a scanf? if so, how do i store their response? scanf("%d?

thank you i was getting an undefined symbol message but i put the stdio.h header and it went away

Code:

#include<stdio.h>

main()
{
int x;
int r;
char response;
srand( time(NULL) );
do{
printf("I have a number between 1 and 10.\n");
printf("Can you guess my number?\n");
printf("Please type your first guess.\n");
scanf("%d", &x);
r = 1 + ( rand() % 10 );
if ( r == x ){
	printf("Excellent! You guessed the number!\n");
	printf("Would you like to play again (y or n)?\n");
}
else
while ( r != x ){
	if ( r > x ){
	printf("Too low. Try Again.\n");
}
	if ( r < x ){
	printf("Too high. Try Again. \n");
}
		printf("Please type another guess.\n");
		scanf("%d", &x);
}
printf("Excellent! You guessed the number!\n");
printf("Would you like to play again (y or n)?: \n");
scanf("  %c", &response);
}while ( response == 'y' );}

finally figured it out thanks quizah couldnt have done it without ur help
