I know there are many threads similar to this one, however, those threads didn't really help me out. I am new to C, so I might be just making a silly mistake, but I don't know what I'm doing wrong.
I am trying to create a main menu like this:
Main menu:
1. Play
2. Reset
3. Display
When users press 1, I want it to print play game, when 2 is pressed, I want it to print Reset, and so on.
However, with my code, when user presses 1, it prints "play game", and when users presses 2 or 3, it doesn't print anything.
int main(){
int input;
/*Displays the menu to user*/
printf("Main menu\n");
printf("1.Play\n");
printf("2.Reset\n");
printf("3.Display\n");
printf("please enter something:\n");
input=getchar();
switch(input){
case'1':
printf("play game\n");
break;
case'2':
printf("reset\n");
break;
case'3':
printf("Display\n");
break;
default:
printf("invalid\n");
break;
}
{
getchar();
while(input != '3');
}
return EXIT_SUCCESS;
}
So I know I might be making a silly mistake, but I just can't figure what I am doing wrong. I have also looked at other threads and none them have helped me.
I think you are looking for do-while loop. You want to nest your switch inside this do-while to repeatedly execute it.
Also, note the extra getchar() call to consume the Enter that was typed after the number.
#include <stdio.h>
#include <stdlib.h>
int main(){
int input;
/*Displays the menu to user*/
printf("Main menu\n");
printf("1.Play\n");
printf("2.Reset\n");
printf("3.Display\n");
printf("please enter something:\n");
do{
input=getchar();
getchar();
switch(input){
case'1':
printf("play game\n");
break;
case'2':
printf("reset\n");
break;
case'3':
printf("Display\n");
break;
default:
printf("invalid\n");
break;
}
} while(input != '3');
return EXIT_SUCCESS;
}
