Thread: Question

Hi

Say i want to declare a variable called menu_number (which is obviously used for menu number ) and it needs to be able to hold numbers such as 1,2, etc and also it should be able to hold characters e.g. Q or ?

when declaring do i need to say int menu_number or char menu_number

or possibly is there any other decleration that can hold both characters and numbers?????

ta

datatype int is only for integer values, char is of course for any single character, so i imagine char would be the datatype to use.

thank you nadroj

your welcome

if your mixing numbers and characters, make sure to always use single quotes around whatever the value is, whether number or character. see my short example:

Code:

#include<stdio.h>

int main()
{
    char menu;
    
    menu = 1; // menu now holds the ASCII value of the integer 1, a smiley face when printed
    menu = '1'; // menu now holds the number one '1'
    
    menu = 97; // menu now holds the ASCII value of number 97, the charcter 'a'
    menu = 'a'; // same as previous statement
    
    menu = '5';
    if (menu == 5) // this will be false, because the _value_ of menu is number '5', not ASCII value 5
         printf("menu is '5'\n");
    
    return 0;
}

hope it helps

very helpful indeed

i have another question though. the thread is called "closest value" can you please have a look?
