Question

THIS IS HOMEWORK. thought i’d let you know. if you could point me in the direction that would help me discover why this error is happening, i’d appreciate it.
http://pastebin.com/hDUpfrsu is my current code (included below). why does it return ONE when i enter (in this order) 5, 6, 7 or other sequences?

#include <stdio.h>
#include <simpio.h>
#include <genlib.h>

/* finds the minimum among three integers using minimal amount of relational operations */

int main()
{
    int myNumbers[2];
    bool lowest;
    printf("Enter the first integer...\t");
    myNumbers[0] = GetInteger();
    printf("Enter the second integer...\t");
    myNumbers[1] = GetInteger();
    printf("Enter the third integer...\t");
    myNumbers[2] = GetInteger();

    if (myNumbers[0] < myNumbers[1] && myNumbers[0] < myNumbers[2])
    {
       lowest = myNumbers[0];
    }

    if (myNumbers[0] > myNumbers[1] && myNumbers[1] < myNumbers[2])
    {
       lowest = myNumbers[1];
    }

    if (myNumbers[0] > myNumbers[2] && myNumbers[1] > myNumbers[2])
    {
       lowest = myNumbers[2];
    }

    printf("\n%d", lowest);
    getchar();
    return 0;

}

Answer 1

A few issues:

• lowest is defined as a bool, it should be an int with how you are using it

• myNumbers[2] is an array of size 2, it can only hold 2 numbers. Change the size declaration to 3.

• Consider what would happen if two or more of the values were equal…
