Question

I\'m trying to write a code that has a lot of comparison

Write a program in “QUANT.C” which “quantifies” numbers. Read an integer “x” and test it, pro

If you are using gcc, you have "luck" because it supports exactly what you want by using a language extension:

#include 
...

switch(a)
{
case 1000 ... INT_MAX: // note: cannot omit the space between 1000 and ...
    printf("hugely positive");
   break;
case 100 ... 999:
    printf("very positive");
   break;
...
}

This is non-standard though, and other compilers will not understand your code. It's often mentioned that you should write your programs only using standard features ("portability").

So consider using the "streamlined" if-elseif-else construct:

if (a >= 1000)
{
    printf("hugely positive");
}
else if (a >= 100)
{
    printf("very positive");
}
else if ...
...
else // might put a helpful comment here, like "a <= -1000"
{
    printf("hugely negative");
}
