List of modifiers in c



In the above table modifier ending with * indicates they are not keyword of c language. These modifiers are called as nothing modifier since there is not any special keyword in which represents those modifiers. If you will not write any thing it then compiler will understand you are writing nothing modifier of those groups.
Meaning of following word in the above table:
nothing: It is not short as well as not long.
not_const:  It is not constant. You can modify.
Not_volatile: It is not volatile.
not_interrupt: It is not sending interrupt signal.
Important points:
1. Nothing modifier must be default modifier of that group.
2. In LINUX GCC compiler there is not any concept of pointer modifier.

Note : All the programs are tested under Turbo C/C++ compilers.
It is assumed that,
Programs run under DOS environment, The underlying machine is an x86 system, Program is compiled using Turbo C/C++ compiler.
The program output may depend on the information based on this assumptions (for example sizeof(int) == 2 may be assumed).
Predict the output or error(s) for the following:

void main()
{
int const * p=5; printf("%d",++(*p));
}
Answer:
Compiler error: Cannot modify a constant value.
Explanation:
p is a pointer to a "constant integer". But we tried to change the value of the "constant integer".
main()
{
char s[ ]="man"; int i;
for(i=0;s[ i ];i++)
printf("\n%c%c%c%c",s[ i ],*(s+i),*(i+s),i[s]);
}
Answer: mmmm
aaaa nnnn

Zoho Interview | Set 1 (Advanced Programming Round)

Third Round: (Advanced Programming Round) Here they asked us to create a “Railway reservation system” and gave us 4 modules. The modules were:
    1. Booking
    2. Availability checking
    3. Cancellation
    4. Prepare chart
We were asked to create the modules for representing each data first and to continue with the implementation phase.

 My Solution :
