Thread: A simple Menu Problem

Hi I have to make a menu for a general case using just if else statement and do-while , while and for loops .
Also for the choice 1 and choice 2 after printing it should show the main menu again only for choice 3 it should exit the program .
Thanks for your help

Code:

#include <stdlib.h>
#include <stdio.h>

int main()
{
	int choice=0;
	
	do{
		printf("Please select one of the choice\n\n");
		printf(" 1) Calcultae resistance value\n");
		printf(" 2) Help\n");
		printf(" 3) Exit\n");
		
		scanf("%d",&choice);
		
		if (choice<1 || choice>3) 
		{
			printf("Invalid choice\n");
			printf("Select again\n\n");
			choice=0;
		}			
		
	}
	while(choice<1 || choice>3);
	

	
do {
	
		
		if (choice==1) 
		{
			printf("The value is\n");
			choice=0;
		}			

		
		
		else if (choice==2) 
		{
			printf("The help menu  \n");
			choice=0;
		}			
		
	

	} 
	while (choice!=3 );

	system("exit"); 
	return 0;
		
}

I'd say you don't need the second loop, and consider changing the conditions of the first loop to ... } while ( choice != 3 );

Then do the if-else tree in the first loop.
