Thread: truth table, inputting values, determine true or false, show values on truth tables,

hello

im stuck on this problem.

A truth table shows the results of values when combined in certain ways.write a program to show truth tables for combining true and false values using the and operator and or operator. print out the results as the values of the "and" or, "or" exspression (0 or 1)

variables
T variable with true value
F variable with false value

execution

AND Truth Table OR Truth Table
T F T F
T 1 0 T 1 1
F 0 0 F 1 0

I have no idea as how to do this. I started by defining the T and F values as 1 and 0 respectively.
problem is I have to use logical operators and I think if statements. the chapter im reading at the moment is about if, if else, switch, break and logical operators and expressions.
so I think I would have to scanf something, then compare/test it using && for AND table. it shows two T in AND table. so....
if(T ==1 && F == 1)

im not sure how to do this. I know that for AND to work it would require two of the same thing. the false is both zero, is this not two of the same thing?
I think the problem is getting truth tables right. but the programming part is still causing me the most problems
if anyone has a starting point, beside "go learn truth tables, then go learn C", I would really appreciate it.

thanks

Sounds like a good start.

You might be over-thinking this - you don't necessarily need "if()" statements.

Consider this simple example:

Code:

#include <stdio.h>

int main(void)
{
    printf("%d, %d\n",0&&1,1&&1);

    return 0;
}

It's not exactly what you need, but should illustrate how can approach solving the problem.

so I think I would have to scanf something, then compare/test it using && for AND table.

The assignment, as you stated, requires you to print out a table. I don't see any need to get user input, based on what you've provided.
